While fine-tuning a technical workshop for next week, my co-presenter and I realized that our comment of "don't forget these knowledge base articles!" (see terminology note below) wasn't very helpful. You used to be able to go to and type in a knowledge base/technical article number like 23025. That would bring up "FAQ:… (Show more)

I'm currently creating a spatial database using Oracle Spatial and it lists both EPSG 4170 and EPSG 4674 as SIRGAS for SDO_GEOMETRY type. The problem is when I try to transform from WGS 84 (EPSG 4326) to SIRGAS. If my table is defined as EPSG 4674, I get an error about different dimensions. If my table is defined as EPSG 4170, the transformation… (Show more)

I am working in a State Plane/NAD83 projection.   I am adding a WMTS service that is is WGS 1984 on someone else's set.   When the transformation window came up, I chose WGS 1984 to NAS 1983 V.   But now I am realizing that I should have said none and let it project on the fly.     So I close ArcMap, remove the connection file from the ArcCatalog… (Show more)

I want to make an accurate map of the location of some plants in a garden. Is there some system for surveying features that are really close together? I wanted to add each plant to a table and track their growth/spread/decline over time. I can't really use GPS they just show up as a big mass of points.   Thanks

I have a table of almost 700,000 records that I would like to plot as points. There is an X field and Y field stored as lat/long (e.g. 40.04746, -75.233316). However, all of my other data is in NAD 1983 State Plane Pennsylvania South FIPS 3702 Feet. I cannot get the table to plot correctly over my existing data. In fact, it plots somewhere in… (Show more)
