Requirements for source data of exporting layers of DTM to the geo database ArcSDE Oracle |
In the geo database ArcSDE Oracle can be exported DTM scale 1: 25 000, based on the digital classifier viet25t.rsc. For maps of scales of 1: 50,000, 1: 100,000 and others, their classifiers must be prepared accordingly for the same requirements as those specified for the classifier viet25t.rsc. It is recommended that you export to a pure geo database ArcSDE Oracle. Before exporting to the geo database ArcSDE Oracle must undergo the necessary control procedures. The exported DTM must have the installed code EPSG. It is recommended that the code EPSG of the exported map and the codes EPSG assigned to the tables of DTM layers in the geo database ArcSDE Oracle are met. In the geo database Oracle ArcSDE, the parameter SRID is responsible for this. The SRID value of the metric field, which indicates the coordinate system that is in the database EPSG, corresponds to the code EPSG (code SRID = code EPSG). The belonging of an object to a specific layer of DTM is determined by the short name of the object specified in the digital classifier of the map. The short name of the object in the classifier must match the table name in the geo database ArcSDE Oracle, which is responsible for storing the data of a certain layer of DTM.
