Buen dia estoy intentando Crear un proyecto con la royeccion local utilizada en mi ciudad, pero cuando la cargo a Pix4D me arroja el siguiente error: [Warning]: Warning w9020: GDAL Error \<6\> Cannot find coordinate operations from `PROJCRS["MAGNA-SIRGAS / Cali urban grid",BASEGEOGCRS["MAGNA-SIRGAS",DATUM["Marco Geocentrico Nacional de Referencia",ELLIPSOID["GRS 1980",6378137,298.257222101,LENGTHUNIT["metre",1]],ID["EPSG",6686]],PRIMEM["Greenwich",0,ANGLEUNIT["Degree",0.0174532925199433]]],CONVERSION["unnamed",METHOD["IGAC_Plano_Cartesiano"],PARAMETER["False_Easting",1061900.18,LENGTHUNIT["metre",1,ID["EPSG",9001]]],PARAMETER["False_Northing",872364.63,LENGTHUNIT["metre",1,ID["EPSG",9001]]],PARAMETER["Longitude_Of_Center",-76.5205625,ANGLEUNIT["Degree",0.0174532925199433]],PARAMETER["Latitude_Of_Center",3.44188333333333,ANGLEUNIT["Degree",0.0174532925199433]],PARAMETER["Height",1000,LENGTHUNIT["metre",1,ID["EPSG",9001]]]],CS[Cartesian,3],AXIS["easting",east,ORDER[1],LENGTHUNIT["metre",1,ID["EPSG",9001]]],AXIS["northing",north,ORDER[2],LENGTHUNIT["metre",1,ID["EPSG",9001]]],AXIS["ellipsoidal height (h)",up,ORDER[3],LENGTHUNIT["metre",1,ID["EPSG",9001]]]]' to `EPSG:4979’ Como puedo solucionar este problema? ---

Hola @luisfer099 Bienvenido a la Comunidad de Pix4D. Por favor nos puede enviar el reporte de calidad y archivo log del proyecto? Por favor vea que los archivos personalizados prj requieren de una estructra especifica para que sea aceptado por nuestro producto. Por favor vea el siguiente enlace: > **[How to obtain or create a .prj coordinate system syntax file](https://support.pix4d.com/hc/en-us/articles/202559979-How-to-obtain-or-create-a-prj-coordinate-system-syntax-file)** > > To work with a coordinate system that does not exist in the Pix4D database, a .prj file needs to be imported into PIX4Dmapper. The .prj can be either downloaded online or manually created. > Download... Espero que esta informacion le sea de ayuda. Le deseo un excelente dia! Saludos cordiales ---

Buenos dias te envio adjunto el log y el prj, porque el informe de calidad ni siquiera lo ha dejado hacer [Magna Cali.prj](https://community.pix4d.com/uploads/short-url/rXydHpJeag6jRSneQdDxq8kK9gZ.prj) (435 Bytes) [Tramo 3-6.log](https://community.pix4d.com/uploads/short-url/eZjQCtwQoRILMlq7u9Qv0EMhwCA.log) (543.4 KB) ---

Hi Luis, I checked the .prj file. The script looks fine. I found it is the same as the one .prj file downloaded here: [Spatial Reference SR-ORG:7664](https://spatialreference.org/ref/sr-org/magna_cali_valle_del_cauca_2009/). It is a little different than the one from [EPSG.io](http://EPSG.io): [MAGNA-SIRGAS / Cali urban grid - EPSG:6249](https://epsg.io/6249). Because the coordinate reference system can be easily and unambiguously identified with an EPSG code. Could you please download the one from [MAGNA-SIRGAS / Cali urban grid - EPSG:6249](https://epsg.io/6249) and see if it works with PIX4Dmapper? ![](https://global.discourse-cdn.com/pix4d/original/2X/9/94c340fdd3a7728fb43a4fc282ba69bdd9e0e841.png) For more information: [Coordinate reference systems and 2D projections](https://support.pix4d.com/hc/en-us/articles/202559849-Coordinate-reference-systems-and-2D-projections?source=search) I hope this helps. Sincerely, Rosana (she/her) – (Traducido) Hola Luis, He comprobado el archivo .prj. El script se ve bien. Encontré que es el mismo que el archivo .prj descargado aquí: Referencia Espacial SR-ORG:7664. Es un poco diferente a la de [EPSG.io](http://EPSG.io): [MAGNA-SIRGAS / Cali urban grid - EPSG:6249](https://epsg.io/6249). Porque el sistema de referencia de coordenadas se puede identificar fácilmente y sin ambigüedades con un código EPSG. ¿Podrías por favor intentar descargar el de [MAGNA-SIRGAS / Cali urban grid - EPSG:6249](https://epsg.io/6249) y ver si funciona con PIX4Dmapper? ![](https://global.discourse-cdn.com/pix4d/original/2X/9/94c340fdd3a7728fb43a4fc282ba69bdd9e0e841.png) Para más información: [Sistemas de referencia de coordenadas y proyecciones 2D](https://support.pix4d.com/hc/en-us/articles/202559849-Coordinate-reference-systems-and-2D-projections) Espero que esto le ayude.
