The ISO 3166-1 official site is probably the most updated source for the two-letter codes. Unfortunately, they don't have the alpha-3 online, quoting their site: Where can I find the ISO 3166-1 alpha-3 country code for free download on the ISO 3166/MA Website? Nowhere. The alpha-3 code is not made available free of charge. You can buy the ...

I am afraid I disagree with you. I think the ArcGIS help/forums/blogs/vids/etc give a great perspective on what you can achieve with the ArcGIS range of products. Your not limited to Python to manipulate your spatial data. You can still use VBA at 931 and 10 to access the ArcObjects library, or you could take it a step further and use .NET to do all sorts ...

If you want to periodically update your list, you could scrape one of the sources and parse its results into a useful format. I've done so here for converting the Wikipedia country code list into a CSV: import csv import urllib2 from BeautifulSoup import BeautifulSoup opener = urllib2.build_opener() opener.addheaders = [('User-agent', 'Mozilla/5.0')] url ...

I think this is a very interesting question. The only problem with it I think is the tags. Most people loving the alternatives will miss this one since it is not tagged "open-source" or anything else that broaden the audience. I am not experienced enough to give a give an answer from very many aspects, but... I did my first things in gis in Arcview 3.x ...

NERC & FERC are going to be your best bets in getting correct data. http://www.ferc.gov/ http://www.nerc.com Not only will you most likely have to pay for the data, but I don't believe you can have access without certifications and clearances (national security threats, etc). Both of the resources above should help you find what you need to do to get ...

Found this collection of links with some archaeological datasets. It's just for UK though. Here's a teaser ARCHAEOLOGICAL DATA Source – BAA, Oxford Archaeology and Wessex Archaeology. Data – Archaeological data for Stansted and Heathrow Airports. Excavations by Framework Archaeology 1998 to 2004 Format – Various, including ESRI format. Licence – Creative ...

The USDA Data Gateway has layers available for 1:12k quad footprints. Not sure if you can fetch the whole U.S. or not, but you can get them by state. Also, you can drag a custom AOI onto the map and get some pretty big chunks it looks like.

A shapefile of the TZ timezones of the United States Last data update: September 30, 2012 The tz_us shapefile captures the boundaries of the TZ timezones of the United States, as of TZ 2012c. The geometries are entirely derived from the countyp020p and timeznp020 shapefiles provided by the National Atlas. All the TZ timezones of United States ...

Depending on your level of accuracy I would suggest the following: Low level Accuracy Use QGIS for Android (free and has a gps toolbar) along with your tablet or handheld native gps High Level Accuracy Use QGIS for Android along with your vendor gps

GIS Data Depot has statewide vector data, including hydro data. I routinely look to the state DNR for GIS data too, for example the Minnesota DNR GIS Data Deli has a wealth of data. USGS Earth Explorer is one of the best sites for remote sensing data. Hydro1k Database from EROS has a good selection of hydro related data including: Elevation Compound ...

I found the site below (credit to Robin Wilson @robintw) to be very interesting. There is a description of all datasets listed and it is organized by themes. www.freegisdata.rtwilson.com Furthermore, it has been updated several times and it is as complete as I can tell.

Most of the data that's available on the National Map is available elsewhere too but where to get it depends on what dataset you're after. You specifically mentioned hydro data, the National Hydrography Dataset is available here in file geodatabase format by state. The high-resolution NHD is what's used on the National Map site.

This is not generally free data. Two providers I've used are Platts and Ventyx. Costs are roughly the same (not cheap!) and I've found the Ventyx stuff to be more detailed though Platts has been better on occasion.

i dont think info like this in free GIS sources existe. you can try to use arcscan to scan a map and make it a shp file. http://gis.cbs.gov.il/shnaton57/all_israel-2006.pdf we did something like this to a map of tel aviv in a gis-database course in baraln

http://www.naturalearthdata.com/downloads/ has 1:50M rasters of the Ocean Bottom (http://www.naturalearthdata.com/downloads/50m-raster-data/). All their data is public domain so there are no worries about licenses.

Carta topográfica escala 1:50 000 Three major scales are available: 1:1,000,000; 1:250,000 and 1:50,000. The DRG maps in the scale of 1:50,000 are being issued and as of today (August 2008) about 85% of the country is available.. They have the same format characteristics as the 1:250,000 ones. The 1:50,000 maps have shading to help in the terrain ...

For ocean bottom basemap (no contours). I recently noticed the ocean basemap release. arcgisonline ocean (rest endpoint) There are some pointers for using it with other basemap extents and also, more information and several other good links for oceanic data (including disputed maritime boundaries) on the esri blog archives.

This is the reality of making the toolset drive the database and not the other way around. You sound like you are in the position where you need a compreshensive database structure, one that you can derive reports, create updates, publish maps, etc. with or without the GIS part. Freeing the data from the tool will give you the ability to use an appropriate ...

While I really like ArcGIS, I must admit that the ability to create watch files provided in workstation ArcInfo is sorely missing in desktop. Many are familiar with Excel's ability to record macros. It seems like ESRI could come up with similar capability - even after 10.0 when VBA is retired. For example, Neooffice has the ability to record python ...

On the ArcGIS platform, if you are not doomed to manual work, then you are doomed to do some programming work (not bad for me since I enjoy that sort of thing)! I don't know of a way in 9.3.x to override default values in the geodatabase without resorting to custom tools. This is what I do, especially if it's a set of repetitive edit operations. In ...

CleanTopo2 looks promising, and is public domain. CleanTOPO2 is a touched up and generalized version of SRTM30 Plus, a public domain dataset that combines sea floor and land elevation data of the entire world. CleanTOPO2 comes in three versions tailored to meet different design and production needs. All versions are 16-bit grayscale TIF files ...

You may find that the data for many of the World's developing countries are not the greatest. However, I've found fairly decent data at VDS Technologies the odd time. I've never downloaded anything for Mexico, so let me know if the data are of decent quality. Good luck EDIT -- Hi again. I had a quick peek at that link I sent you. It appears there may ...

Take a look at OpenStreetMap. And Gis Center at Hebrew University too. You may need to contact them by email.

On Europe, there are: CORINE land cover (downloadable from there) LUCAS (see it there).

I haven't looked at the data, but check out this USGS version. There's some other information on this page. I have a feeling that the data isn't reflecting some of the local changes like Arizona not switching to daylight savings time.

Can you import SVG? A modified mercator prj: http://upload.wikimedia.org/wikipedia/commons/5/5d/World_map_(Miller_cylindrical_projection,_blank).svg These are SVG files with just land outlines: http://fastsvg.com/maps/maps.html

Not Mercator but Robinson Projection http://en.wikipedia.org/wiki/Wikipedia:Blank_maps#World SVG imported into illustrator (or inkscape) can be saved as illustrator format.
