GPS GRID TO TOTAL STATION using Civil3d

 

Managing GPS Grid Coordinates in Civil3d

استيراد أو تصدير احداثيات GPS باستخدام برنامج Civil3d 

تحويل (تصحيح) الاحداثيات الجوديزية او الجغرافية الى احداثيات مسقطة او مستوية

Ground distances المسافات الأرضية هي المسافات المقاسة بين نقطتين إما بواسطة المحطة المتكاملة أو شريط القياس.

Grid distances مسافات الشبكة هي المسافات المقاسة بتطبيق تصحيحات المنحدر ومتوسط مستوى سطح البحر وحيود الجويد ومعامل القياس.

.Use Civil3d Import Point Command to Import GPS Grid Coordinates in tow steps

1- The current drawing must have coordinate zone and transformation information defined (see Step 2).

2- The point file format must have a coordinate zone assigned to it (see Step 3).

Remember Translation occurs only and only during Import operations.

Remember Civil3d Import Points Command Results in ->>>> Ground Coordinates (so after importing any farther change in Drawing>Settings>Transformation tab will not affect points that has already imported

 

Use Civil3d Import Points Command to Import GPS Grid Coordinates and Translate that coordinate in to ground coordinates during import operations.

Remember The current drawing must have coordinate zone and transformation information defined (see Step 2).

Remember The point file format must have a coordinate zone assigned to it (see Step 3).

LOCALIZED co-ordinates indicate the measuring distance in the ground distance or straight distance

UTM co-ordinates indicate the measuring distance in the WGS-84 ellipsoid (GPS datum)

Import Result

Remember Now You Can Simply Export the Ground Coordinates to use by Total station (whether Drawing setting set or not)

Remember Now You Can Export the Grid Coordinates to use by GPS (Check Drawing setting Translation) (File Format setting just the same of import)
