Some background; I am working on a university project which includes data from GPS collars on Red Deer in the Netherlands. There are around 21,000 data points for 4 GPS collars (so 84,000 total data points). But I am have issues displaying them on the map. The points should be displayed in the Netherlands (close to Eindhoven) but instead they are… (Show more)

Recommended Projection for Queensland   Melita Kennedy Damien Pyne   Hi Melita.     Any thoughts about a good projection that covers Queensland, minimizes reprojection errors, uses meters as the units and preserves length?   Need to standardize data from  GDA 1994 MGA – Zone 56 (meters), GDA 1994 MGA - Zone 55 and 56 and lots of Geographic… (Show more)
Hello,   I am using ArcMap 10.4.1. My question does not pertain directly to ArcMap, but to an excel 3d similarity transformation calculator I am attempting to develop.  I am using a decent text reference (Datums and Map Projections, by JC Iliffe) that gives me 4 of the matrix (vector) relationships but, beyond setting the provisional values to… (Show more)

I have a raster in NAD83 CA State Plane Zone II (US feet) that I need to project to NAD83 CA Teale Albers (US feet).  When I run the project raster tool, the false northing on the output raster changes from -4,000,000 (what it should be per the .prj file) to -13,123,333.3333.  The difference between the two numbers is a factor of 3.28 so my guess… (Show more)

Hello,   I have tried quite a few means of projecting the shapefile "Tobacco" to "Chicago City Outline" but I need some help. Not certain as to how or why I've been unable to allow either shapefile's coordinate systems to align.   Also, I have been away from GIS for a bit, anyone know how I add an OID to a table or display the XY data for one?… (Show more)

I have editable feature layers that were published on ArcGIS Online that we edit with Collector.   I realize that when I publish my data to AGOL, it is transformed and re-projected to WGS84 Web Mercator, but when I add the data back into Pro, it doesn't project on the fly back into my data frame's coordinate system (NAD83 - State Plane).    It's… (Show more)

I am troubleshooting a query to publish a web map and feature service in a local coordinate reference system. The reasoning behind this request is that the web map and associated feature services will be used in a WebApp Builder app. The app will be used to add and edit points amongst other things. Within this request, there is a requirement to… (Show more)

Hello, I can't figure out the coordinate system used for this X,Y data (example below). It is supposed to match up with the Souss-Massa region in Morocco, with coordinates approximately (WGS84): Lat/Long: 30° 17′ 51.5826″ N, 009° 15′ 01.6594″ W;  (30.29766184° N, 009.25046095° W) UTM: 29 N 475916   3351796 MGRS: 29R MP 75916   51796   X Y… (Show more)
