Hi Everyone   I have a case where I have vector data (crop census polygons) in a LO19_South Africa Projected Coordinate System with a Geographic Coordinate Sytem of Hartebeesthoek_1994. I then added MODIS LST data to my dataframe which has a Projected Coordinate System which reads: Unknown_datum_based_upon_the_custom_spheroid_Sinusoidal (in layer… (Show more)

Hi python snippets arcgis map clip_analysis tool is not working properly for Annotation layer provided the output in another projection system. Anyone else encountered this.   To recreate the issue:   Open python window   set outcoordinatesystem set to another. Try out clip_analysis for annotation layer. The output is not as expected. The… (Show more)
Hi All,   I am struggling with something related to coordinates;   I have been given some coordinates for a cable: they are in excel but I had to modify a bit it as it was with blanks rows and things like that.   the original format of each cell is : latitude: N32 28.5701 longitude : E034 53.1880   so in order to import all the coordinates… (Show more)

I realize there are already many questions and answers out there related to this issue.  However, I continue having a difficult time pinpointing exactly which transformations I should use.    Essentially, I have GPS data that was post processed against the local CORS stations in Pathfinder Office using the reference position from base provider… (Show more)
What is the best way to re-project NAD83(86) to NAD83(2011) without changing the x y coordinates?  We have a been processing survey data for the last few years from text files that are referenced to HARN, CORS96, 2007, or 2011 (presumably what local surveyors have used over the last 10 years with network GPS receivers) and importing them directly… (Show more)

I'm currently developing a Python Module to reproject shapefiles and CAD drawings (DWG, DXF) that have known and unknown coordinate systems. The code below deals with the known coordinate systems of the shapefiles of which there are 1500 shapefiles and 3600 CAD drawings. I realize that there are limitations in being able to identify the correct… (Show more)
Hi! I'm a new user of arcgis I downloaded vector data layers from one website and got an .tsv document that includes coordinates. That's going to be my map. I put the vector layers on new map and also .tsv positions. looks correct but since it's data about Netherlands, everything is in WGS1984 but top of netherlands looks flattened and my labels… (Show more)

All, Generally I work on data in the UK but am currently working on a project processing data for the whole of Latin America, so every country South of Mexico all the way to Argentina.   I am doing a load of network tracing using gROADS and had projected this into the South America Equidistant Conic. In some cases I am generating routes starting… (Show more)

Hi all, I am writing to ask some help/clarifications about data frame, coordinates and projections. I do not use GIS very often and I have a big gap in cartography. I use ArcMap 10.2 Desktop someone sent me a layers package. I imported the layers into a new empty document. The data frame now gets the layer's proj. coordinate system and… (Show more)
