Using raster data in Netlogo

I am trying to replicate the procedure described on page 111-114 in AGIS. The generated clipped population data file cannot be read into NetLogo. After some digging, here is the problem and the solution is really simple: just add '-co force_cellsize=true' to the text box for additional command-line parameters.

Chinees GIS resources

Here is a list of useful Chinese GIS resources:

1. CHGIS (download and CD)
2. China Dimensions
3. CloudMade (dowload)
4. GRASS-Wiki

OpenGeoDa, again

Another new release of OpenGeoDa is out, but the same problems persists: while the Linux version opened .shp files with Chinese names without problems, the windows version crashed.

Now the new version also works on Ubuntu 11.04 64-bit.

OpenGeoDa

The Linux version of the OpenGeoDa seems to be more stable than the Windows version: I was able to open some shape files with Chinese file names under Ubuntu Linux but not under Windows 7 (simply crashed).

Now the problem is that OpenGeoDa does not seem to run on Ubuntu 11.04 64-bit: no error messages and no hints, really weird...

Using shape files in R

Here is a good demo. Here is another one.

Qgis and google map

Here is an illustration of how to combine them together. This post explains how to do geocoding.

This provides some helpful information.

OpenGeoDa

The new version of the fabulous open source GIS software, GeoDa, called OpenGeoDa, has a Linux version as well as win32 and apple version. I have not tried it, but this is really a great news!
