Some previous posts have starting discussing LiDAR data in Ontario, Canada using the PCS: NAD83 CSRS v7 (epoch 2010). This is related, but more specifically about how ArcMap handles some of these projections and their differences. Hoping Melita Kennedy is watching this thread   We are using both ArcMap 10.6x with some partner agencies using… (Show more)

Hello,   I am using ArcMap 10.4.1.   I have a base map that has the "GCS_WGS_1984" geographic coordinate reference system, it is my understanding that this reference system is referring to a 3d coordinate system.  However, if I export the map, I assume the map is actually projected to a flat image, especially since it appears on a flat computer… (Show more)

Hello Everyone,   i have a (maybe real simple) Problem. I want to add Point Data using X/y-Coordinates based on two different excel-tab. As a basement-layer i use official Data UTM Zone 32 (25832). The first adding is no Problem, die x/y Data is given in N and E collum with Values like:   N E 2689100 4337000 2689100 4341100 2690800 4341200… (Show more)

Hello,   I seem to be having a problem with my feature class coordinate systems.   I have changed the coordinate system of a feature class many times but it still keeps reverting back to the coordinate system of the feature dataset.   Can someone help me understand the issue?

Hello,   I am using ArcMap 10.4.1. I would like to turn off the "On the Fly Projection" capability temporarily if possible.  Is it possible to do this and if so, how can I turn it off?

Hello,   I am using ArcMap 10.4.1.   I would like to match the datum between AutoCAD and ESRI ArcMap.  However, I do not see the datum in the AutoCAD selections, comparing the WKT ESRI information and the AutoCAD options.  The coordinate system I am looking for in ArcMap is designated as LL84 in AutoCAD, which is the WGS84 coordinate reference… (Show more)

Hello,   I'm on lab 5 (image attached) on the Maribeth Price "Mastering ArcGIS" book. My problem is that I'm adding a basemap from ArcGIS Online but the coordinate system/projection does not align with the current map. So, I try to project it, but I can't find the layer in ArcCatalog, it just isn't there because the map I'm using doesn't have a… (Show more)

Let’s say the latest version of ArcMap includes the definition of your country’s latest coordinate system and you would like to use it in your version of ArcMap. For that you need to export the new definition and import the coordinate system to your software. In this post, I demonstrate how you can perform this operation using the example of… (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)

I have traced the outline of an area in Google Earth. Having saved the KMZ I've converted it to a shapefile and then reprojected the shapefile to Arc 1950 UTM 35s (using transformation 8). My data frame is in Arc 1950 UTM 35s. In the dataframe properties I have set a transformation to WGS84 (using transformation 8).   When I add the basemap… (Show more)
