The state BLM office pages often have a version of the data. Colorado for example. However I've found that version may or may not match the one on Geocommunicator - as the data stewards the state version may be more up to date / recently revised (and I've seen the reverse too, where the communicator version was more recent than the state's). This page lists ...

You should check out Geonames. Get one of the country files which has different files on different themes.

I have addressed the topic in a previous question that was partially-related to this one. That being said, here are the places that I know of off the top of my head that have publicly-available parcel data in shapefile form. Through the Southern California Association of Governments (SCAG), you can obtain parcel shapefile data for Imperial, Los Angeles, ...

I am not sure the parcels of the entire state are readily available for free. You may have to look for it on a county by county basis, which may be laborious for 58 counties. This page has a link to the GIS site for each county: http://www.coordinatedlegal.com/gis.html The State of California Geoportal website has downloadable parcels for selected ...

You do not say if you are in academia? If you are then the obvious place to go would be edina and digimap. If you are not then have a look here for free elevation data. Of cause you could go to OS the national mapping agency of the UK and get a 50m terrain model...

Free of charge i would say: Get either ASTER or SRTM from earthexplorer. Both are available at 1 arc-sec., respectively ~20m vertical rmse.

No, you need to create a new column with the right datatype and parse the data from the old column to the new column (guess your using shape files). A new column can be made with the table manager and the update with the field calculator.

If you download the shapefile you will have what is necessasry to get started. The full file (all of the world) is around 2.9GB. The each feature (protected area) has attribute information about name, protected area type (ICUN standard), country code and more. From here on you can do things two ways: Use a desktop tool to produce a kml-file which you ...

Like Chris W mentioned, http://datagateway.nrcs.usda.gov/, is another resource option for PLSS data. IIRR NRCS pulls a copy from Geocommunicator/BLM, stores and distributes it through the datagateway. Couple things to note, on the datagateway main page, don't use the PLSS download link to the left under browse by subject. It's take you to the ...

what are your desired formats and resolution (temporal and spatial)? A quick search found many global products derived from MODIS, e.g.: Gross Primary Productivity 8-Day L4 Global 1km https://lpdaac.usgs.gov/products/modis_products_table/mod17a2 Terra/MODIS Net Primary Production Yearly L4 Global 1km ...

Step 3 of your list is definitely wrong in most cases. It spoils your data, because it does not change the coordinates itself, only the CRS. Instead, you have to save the data from the untouched CRS to another filename and CRS. For the Google background of the Openlayers plugin, project CRS and the CRS of the Google layer must be EPSG:3857. Other layers ...

Well this is confusing. Try to use short names because sometimes long names might cause you problems. eg. "dem_map-AlbSRTMdem" don't use "-" in names. Try "_" and make names shorter. Perhaps that is your problem (according to what I see).

Here's a fuller answer about the synthetic aperture radar (SAR) data available from the Alaska Satellite Facility at no cost to users. The datasets include Seasat (1978 data newly processed in 2013), InSAR, PALSAR (including radiometrically terrain-corrected products), RADARSAT-1, ERS-1, ERS-2, JERS-1, UAVSAR, AirMOSS, AirSAR, and more. SMAP data will ...

Revisiting an old topic, but some might benefit from this link http://www.eia.gov/maps/layer_info-m.cfm Not particularly high resolution, but it does show many of the major pipelines.

Maponics would love to supply you with the best neighborhood boundaries available. If nationwide drops of shape files are too large or beyond your budget, you can also use our API that enables you to download just what you need by attribute, geographic window or ID. In addition, we also have "Context" data that is associated with our neighborhoods, carrier ...
