How to determine the native resolution of a projection?

How to determine the native resolution of a projection?

Note that by calling nominalScale () on the ee.Projection returned by projection (), you can determine the native resolution of the image. The native resolution is the nominal pixel scale in meters of the lowest level of the image pyramid.

How to normalize projection in Google Earth Engine?

When you display images in the Code Editor, inputs are requested in maps mercator. Consider the following simple operation on a MODIS image, which has a sinusoidal projection: // The input image has a SR-ORG:6974 (sinusoidal) projection. // Normalize the image and add it to the map.

What happens when you call projection on an image?

Because each band of an image can have a different scale and/or projection, if you call projection () on an image with at least one band that doesn’t have the same projection as the others, you may see an error like: Image.projection: The bands of the specified image contain different projections. Use Image.select to pick a single band.

Which is the default projection for Google Earth?

An image which is a composite or mosaic of input images with different projections will have the default projection, which is WGS84 with 1-degree scale. For example: If you try to use an image like this in a computation, you may see an error like:

How to enable or disable orthographic projections in RealityCapture?

In the Display part of the ORTHO context menu, you can enable or disable the display of some selected features on the orthophoto (see the picture below). In our example, we have enabled the display of the ground control points, the reconstruction region, and the pivot. You can also fit the image to the view by selecting Reset view.

How big is an ortho projection in pixels?

The Width and Height define the size of an orthophoto in pixels (the ones previously defined in the Ortho Projection tool), and Units per column/row pixel defines ortho pixel size in coordinate system units (in our project 0.021 m, which is 21 mm). You can also see the calculated surface and volume here.
