RasterToPoints convertidos não foram posicionados nos centros das células

Question

<\/HEAD>Prezados, Sou um iniciante muito novo no ArcGIS e estou usando o ArcMap para Desktop 10.4.1 para converter arquivo raster tif em shapefile (pontos). O problema que tive é que os pontos convertidos não foram posicionados nos centros das células que eles representam, como pode ser visto na imagem anexada. Por favor, me ajudem a resolver o problema. Agradeço desde já. <\/BODY><\/HTML>

Dear Steve

Thank you for your e-mail. My reply to your your questions as below.

1) ArcGIS 10.4.1 for Desktop

2.1) Input raster was NDVI TIF file obtained by remote sensing technique.

The coordinate system is ENU.

2.2) For output points, I used ArcMap Tool to convert raster to point,

so I do not know which coordinate system of the output points.

3) No environment was set

I am looking forward to your further advice.

Hi Nang, see this help topic for information on the tool behavior. One possibility is that the tool's Processing Extent environment setting can cause the points to shift off-center. Setting the Snap Raster to your input raster file may fix the issue. http://desktop.arcgis.com/en/arcmap/latest/tools/conversion-toolbox/raster-to-point.htm
