+ibycus Posted April 2, 2008 Share Posted April 2, 2008 (edited) Some here will be familiar with my Canadian Topo Maps. Well, on March 31st, the US Census Department released all kinds of fancy new data on to their website, including features like rivers, lakes, streams, roads (with names and address information), power lines, some trail information, etc. Unlike the Canadian data source, there is no topo information on these maps. (While topo data is available for the US, I haven't found one that splits the data by county, which to do manually would be rather difficult). Anyways, I've taken a 'first pass' at getting these maps on to a Garmin Unit. They seem to look fairly good to my eyes, but I have no idea how accurate the data is (Canadian Census data for the roads is ridiculously bad), but on the surface it looks like its not too bad (in many cases there appears to be more detail than what is no my City Navigator v7 maps, my dataset for Alabama that I've processed is ~50MB) Before I go too far, I wanted to make sure that there is some interest. There are a couple of deficiencies in my maps, some of which will be harder to address than others. Weaknesses There is no 'auto-routing' capability on these maps. Its also not likely that this will be there any time soon. Addresses aren't included - these may eventually be included. Data is split by county - this means lots of individual map tiles. This isn't likely to change. Maptiles are named with an obscure numbering system (specifically according the FIPS # of the county if that means anything to you). Again, not likely to change Given that the data is split by county, and counties have irregular boundaries, the map tiles overlap... this is fixable...don't know how big of a deal this is, but its something people would notice. No street level addressing No Topo Data - Not likely to change unless I can find a datasource that splits the data by county...or possibly create a seperate mapset to overlay on these maps. Strengths The amount of data seems to be pretty high. (50MB for Alabama) The quality of the data at least seems good on the surface. Probably relatively up to date data (brand new release) Free. Given the above, how useful would this data be to people? If there is no demand, I likely won't go too far with it. I've got Alabama done, and I've downloaded a few more states (a state takes me a couple of hours to fully process start to finish). If there is interest, I can post my Alabama map tonight. If you're really interested in your home state, let me know, and I'll try to get the data for it downloaded, processed compiled and uploaded.

+JohnTee Posted April 2, 2008 Share Posted April 2, 2008 Without being able to see what maps look/act like in the field in advance, I think it's safe to say that you will find a lot of interest in your maps. I'd really like to see more data on my handheld when I'm caching . . . It's hard to justify spending the $120-170 on Garmin Maps that would be NICE have have vs. I NEED to have (which I don't - ). Probably need to post a reference in here someplace to a How To/Requirements . . . for those without MapSource, or experience in loading maps. Sign me up for Missouri. Alternating with the beginning and end of the alphabet, with a jog in the middle. I'd be happy to send you a dozen preforms (make nice micros) as a token of appreciation. Cache On!

Well, on March 31st, the US Census Department released all kinds of fancy new data on to their website, including features like rivers, lakes, streams, roads (with names and address information), power lines, some trail information, etc. Not new data. Census has had a semiannual release for TIGER data for many years. What is new is that it is in .shp format (also files for Census tracks, block groups, etc.) Anyways, I've taken a 'first pass' at getting these maps on to a Garmin Unit. They seem to look fairly good to my eyes, but I have no idea how accurate the data is (Canadian Census data for the roads is ridiculously bad), but on the surface it looks like its not too bad (in many cases there appears to be more detail than what is no my City Navigator v7 maps, my dataset for Alabama that I've processed is ~50MB) Downloaded some states, myself. My local county had the roads (+) realigned with this release (over 1/3 of the counties still need this done). The roads are now right on their photo locations. Point spacing on curves seems to indicate equal to 1:24,000 scale. Census says the next edition (now to be at yearly intervals) will improve road/street names (some highways in a city now keep the highway number with no indication of the actual street name. Hydo appears to equal (or be) the new NHD24k. Since this was just completed in late summer 2007 this might not apply to all areas. Need to do more checking on this. Railroads are more up to date than BTS's 2007 offering (sometimes out of date by over 30 years). Need to do more checking on this too. After a few quick looks using GlobalMapper, I am going to rethink what data sources I will use for various layers, but I think the Census data could now be used for many. Before I go too far, I wanted to make sure that there is some interest. I would say there would be a lot of interest. IndyJpr, Oz, +others? are doing the 11 western states. The amount of data seems to be pretty high. (50MB for Alabama)The quality of the data at least seems good on the surface. Probably relatively up to date data (brand new release) Free. Given the above, how useful would this data be to people? Agree, agree, agree, and there is always a demand for free. What has not been realized (at least mentioned) is that contours at a comprable scale would increase the data size by 4-9 times, or more. BTW My downloads have also been crashing ever so often.

I tried interpreting those older Tiger/Line files, wasn't worth the effort (and the conversion programs I found to work with them didn't do such a good job) . As I've got routines to read SHPs already this makes the proceedure *much* more efficient (from downloaded files, to completed map of Alabama is took me an afternoon. Arizona took me about 1hr to complete) Downloaded some states, myself. My local county had the roads (+) realigned with this release (over 1/3 of the counties still need this done). Are you sure about that number (the 1/3). I recall seeing a list just recently of counties yet to be done. There didn't seem to be that many of them (mostly in Texas), but the names meant nothing to me, so you could very well be right. I would say there would be a lot of interest. IndyJpr, Oz, +others? are doing the 11 western states. My own goal is a country wide data set. Assuming the data quality from here isn't too bad, it should be feasible.

What has not been realized (at least mentioned) is that contours at a comprable scale would increase the data size by 4-9 times, or more. My Canadian dataset is up to 2.3GB now, I figure I've got about 1/2 the country covered. BTW My downloads have also been crashing ever so often. Good to know its not just me the government is after . Actually I was a bit worried that the university might have killed it, as I'm downloading it to their servers, and then to my hardware (faster connection on their end, then I have a LAN line from their servers to me).

Census intends for the contractor(s) to have the rest finished this year. Probably will show up in the 2009 edition, which would be out before the 2010 census counts. My own goal is a country wide data set. Assuming the data quality from here isn't too bad, it should be feasible. Longest part is downloading the data. My Canadian dataset is up to 2.3GB now, I figure I've got about 1/2 the country covered. We thank you (Garmin may not). It appears to be very good for the realigned counties. You have your act together. The Canada data is 1:50K, while the US may be 1:24K, that might be twice as many points in both the x and y directions and possibly features which might not be shown on the 1:50Ks. With contours, the US dataset could easily go over 10GB. I have not download you previous version yet because the estimated download time is around 3 hours (with high speed DSL - most available in our neighborhood). Did you add Newfound/Labrador? Actually I was a bit worried that the university might have killed it, as I'm downloading it to their servers, and then to my hardware (faster connection on their end, then I have a LAN line from their servers to me). The Canadian site was also crashing for me this weekend. Must be nice to have the download speed a university connection offers. Takes me 1-2 hours per state(CA closer to 3) - but it is still much more reliable than obtaining 10mDEM's from USGS seamless. Quote Link to comment

For instance he already had done Montana and California. Here is the thread: http://forums.Groundspeak.com/GC/index.php?showtopic=185855 My goal is to cover the whole country in a single mapset, I'm also planning on eventually including address information (which I don't think IndyJpr is). In general, I'll probably stay away from areas he's done, but eventually, as I'd like a national mapset, I'll probably continue on in that direction anyways. My processing seems to be a lot less labour intensive than his (mine takes a on the order of about 1hr/state, and the download can be automated. I get the impression his takes much longer). His seem (from what I've seen) to be a bit more selective in the datasources though, so they do have some advantages. Quote Link to comment

I've never liked that program. Way too many settings. I just want to tell it Convert File A to format B. Apparently its not that easy. With the SHPs getting released, it means I can use routines I've had written for years now to interpret them, and bulk output them to mp files with minimal effort on my part.

With contours, the US dataset could easily go over 10GB. I wonder how much of that would be 'necessary' information, and how much is just interpolating between the data. Way back, before I started on my Canada dataset, I was working on contouring areas manually from DEMs. I found my dataset just got ridiculously huge. The reason was I wasn't scaling back my contour interval sufficiently in steeper areas. I found when I went to using the pre-contoured data the government put out, they'd made that adjustment already, and the dataset was much smaller (and in fact I lost no real information even though I cut back the file size). I have not download you previous version yet because the estimated download time is around 3 hours (with high speed DSL - most available in our neighborhood). Did you add Newfound/Labrador? Yep, those are up. If I were you though, I'd use MapUpdate now to get the latest version (http://www.ibycus.com/ibycustopo/MapUpdate.exe) You'll have to fake an existing install though first (just requires the registry settings and directories for the Maps to be present...you can find a sample at http://www.ibycus.com/ibycustopo/regfix.reg, make sure you edit it as required) Alternatively, you can download a subset area (you seem relatively technically minded, so it shouldn't be too tough) but downloading http://www.ibycus.com/ibycustopo/download/filelist.lst, you can then download the individual IMGs from http://www.ibycus.com/ibycustopo/download/ The Canadian site was also crashing for me this weekend. Must be nice to have the download speed a university connection offers. Takes me 1-2 hours per state(CA closer to 3) - but it is still much more reliable than obtaining 10mDEM's from USGS seamless.

If the compiler I use starts to support them... who knows. The 'pretty' maps are done using a DEM that underlays all the data.

Its not bad, but it requires some registry edits to work, and is really taylored to a single datasource, so not really suitable for public consumption. Other program I just finished is one where I can double click on it, and it will start compiling all mp files in a given directory. (e-mail me if that would be of any use to you).

yogazoo Posted April 4, 2008 Share Posted April 4, 2008 How about a screenshot of here: N32.19489 W110.94645 I love that it took you just over an hour to compile the maps while it takes me over 1 day of computer time just to process the contours. Then another couple days to get the water and everything set. I think I've got my method set so I'll probably do Mississippi next (the AF is moving me there soon). I'd never have the patience to do it your way . It looks like Tiger2000 Data to me. Am I missing something? Quote Link to comment
-Oz- Posted April 4, 2008 Share Posted April 4, 2008 I sent you an email. I wish the data had a code for interstates. The old data I used (from my state) has codes for interstate, highway, arterial road, residential, unpaved roads, which is nice. Quote Link to comment

Never spent any time working with the Tiger2000 data, so I don't know how different it is. Advantage for me of this dataset (which is why I'm using it) is that its available in SHP files. (I know there were some sources that made SHPs available of the older datasets, but those typically had limits to how much you could download at once, so if you wanted to download an entire state, it would take forever.).

There is some coding information in there for this kind of thing (in the MTFCC code). Don't recall exactly how its split up. I was planning one of these days to add a little check in my code so that if the "NAME" field contains the right string (i.e. interstate) to add a little shield symbol or whatever.

yogazoo Posted April 4, 2008 Share Posted April 4, 2008 I guess we are spoiled rotten in Montana. We have so much data readily available to us on our State Library website that I forget that most other states have nowhere near. Here's the Link for all of Montana's data. Our Cadastral Data is the cats meow! Ok, OK, I may have a data superiority complex I admit. http://nris.state.mt.us/gis/gisdatalib/gisDataList.aspx Quote Link to comment
+ibycus Posted April 4, 2008 Author Share Posted April 4, 2008 I've just updated my mapset with Montana. I'd be curious to know how this data compares. (I asusme you have some kind of mapset based on your data already). There is definitely some stuff in yours that isn't in mine. Quote Link to comment
