Requirements for source data for import of layers of DTM from the geo database ArcSDE Oracle

To import the layers of DTM from the geo database ArcSDE Oracle containing data scale 1: 25,000, the digital classifier viet25t.rsc, corresponding to structure the geo database ArcSDE Oracle of this scale, must be applied. To import the layers of DTM from geo databases ArcSDE Oracle of scales 1: 50,000, 1: 100,000 and others, their classifiers must be prepared according to the same requirements as those specified for the classifier viet25t.rsc.

To load the layers of DTM from the geo database ArcSDE Oracle will create DTM of format GIS Panorama. The map is created with the parameters of the coordinate system and the projection corresponding to the specified code EPSG. The code EPSG for creating a map should be indicated in accordance with the parameters of the coordinate system used in the geo database ArcSDE Oracle for the layers of DTM.

If the geo database ArcSDE Oracle has layers of DTC with different coordinate systems (spatial data tables have different SRIDs), it is necessary that at the database level it is possible to transform the coordinates into the system specified by the code EPSG of the created map.
