Ich möchte eine vorhandene Shape-Datei nehmen, um eine neue Shape-Datei mit einem anderen Koordinatensystem (Projektion zu Geolocation) zu erstellen.

Hallo zusammen,<\/P>

<\/P>

ich bin ein neuer Benutzer von Arcgis Pro und habe Schwierigkeiten, den richtigen Weg zu finden, um ein Ziel zu erreichen.<\/P>

<\/P>

Ich möchte eine vorhandene Shape-Datei (https:\/\/www.mass.gov\/forms\/massgis-request-statewide-parcel-data) verwenden und ihre Merkmale in Bezug auf die Geometriedaten in Breiten- und Längengrad überprüfen.<\/P>

<\/P>

Das Problem ist, dass diese Datei anscheinend ein projiziertes Koordinatensystem verwendet, während ich die Geometrie in Breiten- und Längengrad benötige. Ich dachte, die beste Lösung wäre, die Quell-Shapefile in eine neue Shapefile mit einer Art Transformation zu kopieren, aber ich habe Schwierigkeiten, die genauen Schritte dafür zu finden (viele Tutorials\/Beispiele verwenden eine ältere Version der Software, daher ist es schwer, die Funktionen zwischen den Versionen abzugleichen).<\/P>

<\/P>

Jede Hilfe oder Vorschläge oder völlig andere Strategien zur Erstellung einer neuen Shapefile oder einer exportierten Datei eines anderen Typs mit Breiten- und Längengrad sind sehr willkommen!<\/P>

<\/P>

Vielen Dank im Voraus!<\/P><\/BODY><\/HTML>

There are several ways to do this. Use the Project tool in the Data Management Tools. Or right click the shapefile -> Data -> Export Features, in the Environments tab change the Output Coordinate System to the Geographic coordinate system you need.

Matthew Driscoll‌ 's suggestion is a good one; perhaps though you could explain your workflow and desired results so that other solutions can be explored.

To start Thank you both for responding! Currently attempting to use the python code associated with

http://resources.arcgis.com/en/help/main/10.2/index.html#/Geographic_Transformations/001w0000000v000000/

So once that attempt is complete, I'll run Matthew Driscoll‌ 's suggestions since they seem very strait forward, and hopefully that is all I need!

In regards to more context of what I am attempting to achieve:

The problem:

I have a MongoDb database which contains a number of GeoJson based points. I am looking to take those points, and search the.shp file ( which contains polygons ) for these points, allowing me to get feature data associated with the shp/dbf files for those points.

Related information:

The MongoDb database and related infrastructure is running under a Node.js environment, so ideally I'd like most of my processing to be done in node. I have a node.js library that can parse a shp and dbf file directly ( https://www.npmjs.com/package/shapefile ), and verified this specific shp and .dbf files can be read by the library. However to my dismay, the geometry was outputted as an array of array of numbers that clearly were not latitude/longitudes, so clearly some sort of transformation is needed.

So I have been looking for a way for ArcGIS Pro to generate a shapefile with the coordinate system I need, or to export as a different file format with the coordinate system I need and feature data I want. Csv output seemed strait forward except it doesn't seem to export the polygon data at all ( documentation indicates it only works for point data ). I saw there was a tool for geojson which seemed ideal but it "seemed" to hang in processing, potentially due to the size of the Mass Gis file (.shp file is over 1gb, and .dbf file is over 2gb in size). So potentially part of the problem is I need to cut the files up into smaller chunks. Either way the primary hurdle is getting the coordinate system to be based in latitude / longitude and available in a file format I can parse ( csv / json / shp / xls / xml / kml / realistically most common file formats )

Again, thank you for taking the time to make suggestions!

A quick follow up, following Matt's suggestion I was able to generate a new .shp file with a coordinate system that contained latitude/longitude based polygons.

Thank you for your help!

Make sure to mark it as correct!
