I'm assuming the page numbers are pulled from the attribute table of the layer you are using to create the DDP and can therefore add a dynamic attribute. If you have two text boxes one on each side for odd and even pages I think you should have two separate fields in the attribute table, one for odd the other even which would only display the text on the ...

It seems like you are looking for a couple of different resources. Now, I actually found an interesting administrative resource you may want to look into here. From what I can tell, it is tax roll data that lists information on businesses that include address, and census block group id, thus allowing it to fit into GIS models. Not only that, according to the ...

OpenStreetMap is your best bet. You can download the data using built-in tools in QGIS. See the step-by-step instructions at http://www.qgistutorials.com/en/docs/downloading_osm_data.html

Cloudmade do extracts from OpenStreetMap data suitable for loading into Satnavs or GIS packages. For example, the Florida data is here: http://download.cloudmade.com/americas/northern_america/united_states/florida#downloads_breadcrumbs if you download and unzip florida.poi.gpx.zip you'll see a florida_Eating_Drinking.gpx file which has coords and names of ...

I think your best bet is going to be downloading GIS data for populated places and coastlines (Natural Earth is an oft-recommended source) and performing a proximity analysis using GIS software to exclude all places except those matching some criteria, e.g. within 10 miles of a coastline. Bear in mind the world is a big place, and the coastlines are very ...

The National Hydrologic Dataset offers all hydrology data in 1:100,000 (medium res) or 1:24,000 (high res) for all of the US.

If you want to get a 3D DXF from a SHP (SHPfile generated from DTM with Qgis-Processing-Tools-GDAL/OGR Extraction-Contour), you must: 1) have column with Z values into Table attributes of SHP. 2) open "OSGeo4W Shell Commands" if you have Windows OS. 3) write into shell for example: ogr2ogr -f "dxf" d:\Temp\3Doutput.dxf d:\Temp\contour.shp -zfield ELEV ...

This way it works: For Easting, subtract 108 000 000 from lng, and divide by 600 000 For Northing, subtract 54 000 000 from lat, and divide by 600 000: lng lat E N 177514245 34726053 115,857075 -32,123245 177513828 34726948 115,856380 -32,121753 177508930 34829424 115,848217 -31,950960 177508084 34829842 ...

You might want to checkout the MapBox Satellite layer. It's available under their Basic Plan, which is $5 a month. I believe the layer is distributed as TMS tiles, and you can review the granularity and coverage of the layer before you commit to anything. Admittedly, though, this would be more difficult to apply to your use case, but surely not impossible, ...

For multiple variables, you need multiple nc_def_var() calls. One way to get example code is to create a CDL-based text file the matches your needs, and then run 'ncgen -c' (http://www.unidata.ucar.edu/software/netcdf/docs/netcdf/ncgen.html) on it to get sample c code.

The source data is available at http://www.census.gov/geo/maps-data/data/tiger-line.html. Note that the 2000 series tab provides data in the old ASCII format, but you can get the Census tracts by US state for 2000 in shapefile format from a page off the 2010 tab. Other than that, I can only suggest contacting ESRI.

Cool idea. Accomplishing this will take a couple of steps. I will say I have not tested ANY of the code in this answer. It is possible for errors or syntax issues, but the general idea is there. Here is how you could grab the county extent. var county = document.getElementById("sel_county").value; //Your county select object var queryTask = new ...

A note about GIS data from China; many (all) their datasets are considered national secrets and are very difficult to obtain. Even if you do obtain a copy you could get into trouble. I tried finding similar data for my capstone class and ran into the same problem. If you are serious about working with GIS data in China, the easiest way is complete a masters ...

Usually terrain models derived from remote sensors will have their initial accuracy evaluated using blind control methods. For example with LIDAR, the remotely sensed measurements are often compared to survey-grade control points (the blind control) taken on the ground in various land covers (woods, open areas, etc) to assess the penetration and accuracy of ...

Some literature on this topic: COLOSIMO, G., CRESPI, M., DE VENDICTIS, L., JACOBSEN, K. (2009). Accuracy evaluation of SRTM and ASTER DSMs. In Proceedings of the 29th EARSeL Symposium, Chania, Greece. GOROKHOVICH, Y., & VOUSTIANIOUK, A. (2006). Accuracy assessment of the processed SRTM-based elevation data by CGIAR using field data ...

The National Center for Education Statistics has a database of colleges in the USA. This link provides addresses for colleges, which you could geocode to get coordinates. Maponics provides College Campus boundaries and points for over 2,100 colleges in the USA and Canada. Some details at this link, from which I pulled the image below.

I would recommend you pull the data from the Geonames database. I will tell you that I went through a similar process a few years ago and it is anything but clean. However, you can get a large number of points that you are looking for. You'll want to look in the the following attributes to get started: fclass = 'P' (Places) or 'S' (School) fcode = ...

You can delete a field using OGR SQL and choosing an OGR format which supports the field deletion. Unfortunately GML doesn't support it, so you have to pass through another format, e.g. SHP: ogr2ogr temp.shp input.gml ogrinfo temp.shp -sql "ALTER TABLE temp DROP COLUMN field_to_drop" ogr2ogr -f GML output.gml temp.shp
