Geodetic control network survey
The following works usually are performed:•State Triangulation Network points are found and recognized in the field;•Ground Control points (GCP) and Check Points (CP) are installed and marked with crosses;•Geographical coordinates of both GCP and CP are measured using DGPS;•IIIth or IVth class leveling is performed for both GCPs and CPs implemented in the field.

Field topographic reconnaissanceThe field objects interpretation and reconnaissance include:•information collection about infrastructure objects location and labeling,•making photo of industry infrastructure objects,•information collection about type of landscape, •sorting and preliminary processing of the collected material.

The quality checking includes:
•Checking the conformity, completeness and adequacy of digital data to initial raster orthophoto with all the errors recorded into a file of comments.•Checking the conformity of semantic data in attributive tables to the field reconnaissance data.•Loading together the map sheets on borders. Checking the conformity of the objects for southern and eastern part of the map sheets.•Checking for presence of objects with missing classification codes.•Checking inconsistency and typing errors in the attributive data.•Checking the correctness of geometric topology by standard topology fixing tools for revealing various irrational errors.In the progress of quality checking all separate lines of the same character that were created in different sectors of the map by varying cartographers are merged into one object according to attribute domains code.
