Hello,   we encountered a mysterium here. We have one zip folder which contains a raster file (dem). If we unpack this folder on one laptop, the dem has the right coordinate system (which is ETRS...). If we unzip the same folder on another laptop it hast a wrong coordinate system (WGS...(Northern Hemisphere)).   I have no clue why, maybe someone… (Show more)

Click to view contentGood Morning, we recently reprojected all of our data to State Plane NAD83(2011) using the the Project tool. We projected our data from NAD 1927 StatePlane Wisconsin South FIPS 4803 to NAD 1983 Harn StatePlane Wisconsin South FIPS 4803 feet.  We then defined the projection to NAD_1983_2011_StatePlane_Wisconsin_South_FIPS_4803_Ft_US. After doing so… (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)

Title is the question. Yes I checked AcMap options, Data View tab for the correct settings. Won't work. If I load a new a new ArcMap it works but then I have lost my template which took many hours to build. Incredible waster of time.#
Hi,   I need help on understanding the logic in setting up and using custom geographic transformations in ArcGIS Pro. I think I've read everything I was able to find online incl. several issues here on GeoNet. I would like to take advantage of a Custom Geographic Transformation in the "Project"-geoprocessing tool or as an alternative in the "Copy… (Show more)

Hi all,   i would like to seasonally measure distances and areas inside a rectangle (200 cm x 150 cm) fixed with permanent marks in a vertical wall. The idea was to gain pictures and transfer them to ArcGIS desktop 10.2. So i thought to create a new projected coordinate system with the reference scale based on the dimension of the rectangle… (Show more)

Hello, I am using ArcMap 10.4.1.   I am looking for confirmation of my understanding of the below scenario. I am trying to understand what happens when two different coordinate systems do not align.  The concept appears simple but want to confirm that I am not missing something.  I have attached an image of the Lambert Conic Conformal projection… (Show more)

I have been working with adding in a scale factor parameter but am not able to figure out how to scale about the origin.  Our survey standards require us to scale our data from 0,0.  I need to create a projection that will reduce CAD data from ground back to grid, scaling about 0,0 of the grid.

Coordinate conversion Which is the best practice for coordinate conversion of the features / shape files? I often use the following method Import the xy from excel (know coordinate system) Event layer to shape file Data Management Tools --> Projections and Transformations --> Project - To get the output data in the required coordinate system… (Show more)
