I am particularly interested in location analytics, blending Business Intelligence with spatial analysis. Examples include retail/real estate site selection, trade area analysis, customer research, and marketing through demographic analysis.

I use Python for process and workflow automation, database reporting & manipulation, and developing new spatial tools.

I've been a GIS professional for 15+ years, most of which using ESRI tools (since Arc/Info 7.x). More recently I find myself using more open-source tools (QGIS, PostGIS, GDAL/OGR, web-based tools) and ultimately choosing "the right tool for the job" rather than being tied to a single vendor or toolset.

comment How to rename PostgreSQL/PostGIS columns while importing Shapefiles?
@mapBaker, you are correct. -f is for filename, not column name. Ummm... yeah... I really meant what LR1234567 said :)

It looks like the -f flag can be used for this based upon PostGIS 2.0 pgsql2shp shp2pgsql Command Line Cheatsheet

Can you provide a screenshot of your data, or better yet, a link to a sample data set?

Have you tried converting your data to topojson? By eliminating redundant, duplicated nodes, you may find the file sizes reduce significantly and load time decreases as well.

comment How to hide all fields at once in QGIS 1.7
Never mind about the code... I figured it out. To revert to the default setting, use: layer.setEditType(i, QgsVectorLayer.TextEdit). But is there a bulk on/off in the GUI?

@Nathan W- Has there been any GUI updates to bulk hide/show in 2.4? If not (for non-techies) what is the appropriate EditType to show the fields (opposite of QgsVectorLayer.Hidden)?

I think the "Definition Query" option is the most simple & consistent method to use.

@Allen, please move your "comment" above to an "answer" below and, once StakExchange allows you (I think after 2 days), you can mark your answer as "Accepted" (hit the checkmark next to the answer) to close out this question. Thanks.
