I am a GIS Analyst with a background in archaeology, computer science and general electronic tinkering. I generally know enough to get in way over my head and then work my way back out.

comment How do you hide a feature within a point layer?
+1 For the crazy selection color idea. Ridiculous hacks like that can only be the product of a frustrated ESRI user.

comment Postgresql table won't display in QGIS 2.2
The script was very helpful, I appreciate you sharing it! I don't have a ton to do but I was unsure of how to alter the table correctly. I was able to figure it out from your code - again, many thanks!

comment Postgresql table won't display in QGIS 2.2
I'll just be honest and say I don't know what that is... A link for instructions perhaps? I'm running Postgres 9.1 as part of the OpenGeo suite.

Yup. That did it. Ugh. I'm still learning SQL (obviously) - How do I know when to use the parentheses and when not to?

Also try using just localhost in the instance box, that's what works for me.

comment Problem in multiple dataframe visibility in arcgis 10
The ESRI basemap counts as a raster, so if you're using that in one of your insets it might be the cause of your problem. The only other thing I can think of to check is that the backgrounds and borders are set to none or null.

comment How to avoid creating corrupt Shapefiles during Editing?
I've also had this error crop up while editing shapefiles. My work around was just to do my editing in ArcMap. Obviously that's not a real solution - but - you aren't alone in experiencing this kind of error.

comment Find Direction/Location of point in polygon using Python ArcGIS10.1
If the point is always located inside of the polygon then the centroid could still be used pretty reliably I think. Even when the centroid falls outside of the polygon itself, the relationship between the contained point and the centroid could still identify which 'quadrant' the point is in. It really only becomes an issue in cases when the point falls outside of the polygon.

comment Arcmap fills up full image
The error showing up seems to further indicate that there is a problem with your shapefile. Assuming that it's a shapefile and not a feature class. You could try exporting it to a new copy and trying to run the tool on that. Also, you could start an editing session and look for any weirdness in the vertices of the polygons. If it's a feature class I'd start by compacting/repairing the database. Another thing to try is to turn off background processing, sometimes taking things out of the background gets the tool to run, especially with unspecified errors like this one.

comment How to Deal with Overlapping Coordinates in Statistical Analysis
Totally understandable! To solve your original problem, I'd stick with my first suggestion. Just nudge them off to the side a bit. If it were my project, I'd move each one 1-2 meters away from the original location, at least that way they aren't stacked directly on top of each other.

comment How to Deal with Overlapping Coordinates in Statistical Analysis
My point is that archaeological sites always have area. Points never do. So, by using a point to represent an archaeological site you may be incorrectly limiting the number of other variables that your site is associated with. For example, the relevant variable may be a range of elevations, not a single elevation, and by assigning each site a specific elevation from a point you are obscuring that. Choosing to use points or polygons is a choice that should include consideration of the scale of your analysis, your research question, and what other variables you are considering.

comment How to Deal with Overlapping Coordinates in Statistical Analysis
First off, I'm an archaeologist in North America, I have no experience with European archaeology. That said, I would think that you could use the site reports and maps to digitize the area for each site, perhaps even fairly accurately. If you don't have the maps, then some manner of polygon that relates back to the size described in the report would likely suffice.

Glad you found it useful! If it has solved your issue please mark the question as 'answered' so it will be closed.

comment Computing distance of a georeferenced .jpg to each polygon (town) in a shapefile
Georeferencing the image simply places it in space relative to other data. It's still a raster, not a vector. To get the road and cities into a vector format you need to digitize the line and the points for the city. The link Fezter provided is probably the best place to start.

comment Strange things are afoot with the "Eliminate Polygon Parts' tool
I've encountered this error when coming at if from arcpy and the ArcGIS tool. Regarding the matter of the area, the polygon in question is about 1,000,000 square meters, so specifying an area condition at 1 billion is actually a larger area than the total polygon area.

comment using the “freehand” construction tool
That's a good one too - I really like using undo because you don't have to click anywhere. If you just screw up and click in totally the wrong spot you can just hit ctrl-z and carry on.

comment Are database client files platform specific?
So, are the files specific to QGIS and ArcGIS? Or is it just a matter of making a copy of the set in the ArcGIS folder so they are available to ESRI products as well?
