i don't trust the gc module as much as I do spawning a separate process. The separate process will do the work and will then be killed after the join(). Try adding: from multiprocessing import process to the top of your script then replace: exportAISMap(mxd_path, pdf_path) with p = Process(target = exportAISMap, args = (mxd_path, pdf_path)) ...

I like to use the .emf format--it is a vector format, so you can resize without any issues with pixelation as you sometimes get with raster formats like png and jpg.

Quantum GIS now supports this feature, the resolution can be set and can include an optional world file containing georeferencing information.

"Used digitally" is pretty broad, and depending on how they will be used or distributed might make a significant difference. As would the data type (vector or raster) shown in the map. For this answer, since your question title explicitly says PowerPoint and your body mentions that, that's what I'll address. The first thing to determine is whether what ...

Personally, I use pdf for all maps that will be used digitally. They have the ability to be zoomed in and navigated without losing resolution. There is also a geographic element in Adobe Reader that allows you to display the different layers and information about those layers in a sidebar if needed. I don't know of any general rules, however.

It turns out the Centroid(X) and Centroid(Y) in MapInfo are not the line centre point coordinates in BNG. (However to get around the rounding problem I exported the table as a DBF). Instead, I generated these in ArcGIS instead and got perfect results. I achieved my desired result by calculating differences in X and Y values between subsections and taking the ...

After exploring some options, since your data has a date/time field and you are already using a time slider, it seems the best way to go is using tools specifically aimed at exporting temporal series maps, rather than DDP or definition queries. The help files on the subject mention that you can use arcpy.mapping python scripts to produce time series output, ...

Considering the fact that you are exporting some raster data as well; the best technique, IMHO, is to NOT use the ArcGIS PDF exporter at all but rather export to a high resolution TIFF instead and then convert the tiff using Adobe Acrobat Pro renderer to PDF. (Important note: this only works well with TIFF) You can tweak the rendering options in Adobe if ...

I had an issue similar to the above, and also similar to this: http://osgeo-org.1560.x6.nabble.com/Print-Composer-Rotation-of-Shapefiles-with-transparency-td5100394.html I finally fixed it in the style box of the Layer Properties - I set the transparency in the top Layer Rendering box to 0, and instead changed the layer transparency in the symbol colour ...

I have a solution for this problem. In the Registry search for the folder: HKEY_CURRENT_USER\Software\ESRI\Desktop10.1\Export\ExportDlg\ShowOptionsPanel and change the value from 0 to 1.
