Where can I check the specified maximum and minimum visible scales specified for a layer?

Why cannot I overlay a vector dataset and a raster dataset correctly in SuperMap even though they can overlay well in ArcGIS? They are both in WGS84, and after been imported into SuperMap, the vector dataset displays correctly but the raster dataset display wrongly. Why does this happen?

Why cannot I see the text after importing the Arcgis shp text file? Why does the Arcgis shp text file become a point dataset after being imported into SuperMap?

How can I convert small values for the smarea field of the region dataset imported into the oracle datasource to the real areas?

Why did I fail to generate network dataset from line datasets with all parameters specified correctly?

How can I rotate maps with symbols not rotated?

Why is the color of the image dataset imported from the tiff image white with no features display?

How can I optimize the slow browsing speed of the network dataset in the oracle datasource?

How can I find the differences between two datasets that have slight changes no matter they are raster or vector datasets?

The block object inserted in the CAD has the value of Z scale factor. However, the value cannot be read while being imported into SuperMap. How can I read the Z scale factor value of the block object in CAD?

Can a SIT file have projection file similar to the tfw coordinate file of a tiff file?

How can I perform the dissolve operation for multiple adjacent objects in a region dataset for administrative regions if each of those adjacent objects is composed of multiple child objects?

How can I represent line breaks and connectors if I use oracle datasource to create label thematic maps?

What does a field start with sM mean? Can I modify the field?

How can I change the coordinate system of a datasource? How can I align a scanned image with the data in correct coordinate system?

There are around 200 image datasets with raw data format jpg in the datasource. Sizes of original jpg pictures are between 300K to 8M and the number of images around 8M is no more than 20. However, the total size of these datasets swells to 12.1G after being copied to a sql datasource. Why would this happen?

Why are the x/y coordinate values acquired through querying altitude values for 3D data generated from 2D DEM data totally different with the coordinates of the original 2D DEM data？

While importing the vec format data, I encountered a failure and got an error message telling that the dvc file is missing. Why does this happen?

How can I overlay the vector data with projection belt numbers and raster data without belt numbers?

Why do I encounter the error “Insufficient memory” while opening a dataset?
