Problem with Shape Map / Problema com Mapa de Formas
Bom dia,
Ao carregar um mapa de forma que converti de shape file para TopoJASON, as linhas se apresentam como polígonos no PBI.
1- No GIS, tive o cuidado de transformar todas as formas em polilinhas.
2- No Mapshaper, fiz a conversão de SHP para TopoJASON , neste passo eu não verifiquei nenhum problema.
3- Porem ao carregar o arquivo TopoJASON no PBI, , algumas linhas do mapa aparecem como polígonos ,
Alguém saberia me informar o que esta acontecendo ?e como posso resolver?
Muito Obrigado!

Good morning
When loading a shape map that I converted from shape file to TopoJASON, the lines present themselves as polygons in PBI.
1-In GIS, I was careful to turn all shapes into polylines.
2- In Mapshaper, I did the conversion from SHP to TopoJASON , in this step I did not check any problems.
3-However, when loading the TopoJASON file on PBI, some map lines appear as polygons,
Would anyone know what's going on and how can I solve it?
Thank You!
Hi Wellingtonjr ,
When you convert it from SHP file to topojson file, please try to set it as WGS84 / EPSG 4326.
The problem could lay with the original shapefile’s coordinate or geographic reference system. Some shapefiles with less common map projections that Power BI could not support without severely distorting the image.
Here is a blog that explains it in details that you can refer:
