I spend a lot of time working on fantasy maps, currently I am working on several large shapefiles/geodatabases which in combination cover the whole of northern Africa. I have had a lot of trouble running that much data in ArcGIS Pro, but ArcMap on the other hand, gives me no trouble at all working on such a large dataset. I would suggest working with ArcMap ...

I emphasize that this function might not be useful for everyone. It will depend on what you're trying to do, and your inputs, and how possible it is to do what you're trying to do given your inputs. For instance, if you have a complicated shape with concave sides, forget about it. In my case, I just wanted to cut a box filled with random points down to a ...

A bit late but you should include this from your database perhaps. That will show us which indexes are being used. Connect to your DB with the postgres user , and connect to the correct DB SELECT relname, indexrelname, idx_scan, idx_tup_read, idx_tup_fetch FROM pg_stat_all_indexes WHERE schemaname = 'public' order by 1; that output will tell us if you ...

There's two pieces to the performance pie here: The time to calculate the tagging, which you should break out by doing some test runs with things like CREATE TABLE tract_pt_counts AS SELECT Count(*), tract_id FROM tracts t JOIN pts p ON ST_Intersects(t.geom, p.geom) GROUP BY tract_id The time to update a table in place. This is actually probably a lot ...

Precision of a GPS device depends on how it evaluates the position. A-GPS(Assisted Global Positioning System) Devices : Usually mobile phones. Uses cellular network as well as satellites to triangulate current position. Some Devices even show you altitude with latitude and longitude. GPS (Global Positioning System) Devices: Usually proprietary ...

If it's possible, use your GPS unit to get position & elevation of a known benchmark and then compare that with the official values. Here is a picture of a USGS benchmark. If you can't find the locations of any near you, just contact your USGS local office. If you cannot access benchmarks, see if there is some structure that you can get precise ...

Whenever I have to export many data driven pages, I use a Python script to do all the heavy lifting in the background without having to babysit - and I think it's faster, it feels faster. More or less like the documentation here: import arcpy import re from arcpy import env import os.path env.workspace = "q:\\yourfolder" sCur = ...

I believe that's because your Python is using ArcPy to call Geoprocessing tasks, which are running in 64-bit processes. ArcObjects happens in 32-bit processes.
