Survey - Field to Finish¶
Steps from field work¶
- ?? To be added by Raj and Ram
- Copy the .txt files from the equipment- Controller/Total station, to system using a pendrive (Storing the data- "D:"> "AVSM"> "Water Projects"> Respective project folder)> "TS"/"RTK")
- Cleaning up the .txt files/removing errors (If any)
Feeding the survey data into Civil 3D- by Surveyor¶
- After cleaning up of files, the files are stored in a desired location, to be used as import events into the Civil 3D file
- Open up project in Civil 3D
- Importing of Events (explain the step)
Processing- by Surveyor¶
Initial line work is generated from survey points in the drawing. Points for reconciliation (Changing the point codes) are reported, if any. It is important that there is a fair knowledge of Autodesk Civil 3D for this work.
Post-Processing¶
Final linework is generated on top of the processed linework. At this stage, a drawing is cleaned and prepared for sharing. problems like - overlaps in line-work, proper assigning of layers etc. Points for reconciliation are reported, if any. Post-Processing is crucial to generate correct and standardised survey drawings (in .dwg format) keeping in mind that those drawings will be used to generate shape files (.shp format). Therefore, it becomes important to follow a certain workflow based on compatibility of .dwg elements and .shp elements - for example for creating a shapefile of "Polygon" type, the elements in .dwg should be all "Polylines" of "closed" nature. All features should be in zero " 0 " elevation and the shapefile generated should be 3d type. This has been elaborated here < insert > At this stage, a good knowledge of Autodesk Civil 3D and GIS (to a certain extent) is a must.

Sharing on WebGIS - "GISAF- gis.auroville.org.in"¶
After creating the shp files from AutoCAD, the shp files are ready to be shared on WebGIS platform. Following are the steps to do so.
- Upload and import Raw survey points to GISAF - Before uploading and importing the shapefiles, it is necessary to upload and import the corresponding Raw survey points into GISAF.
- Auto-import of point shapefiles - After the import of point files (RTK and TS), the next step is to Auto-import the points which are point type shp files. Go to Admin> Others> Projects> Select the corresponding project > With selected > Auto- import to GIS Database ( GISAF)
- Upload shp to basket - Zip together all the types of files obtained after saving a shapefile on the system (shp, prj, dbf etc). Follow the same naming standards when creating this. Upload it to the basket in GISAF- Admin> Basket> Shapefiles> click on relevant project> click on relevant sub-project (if any)> upload file> select the zipped file from system> select the category from directory >save.
- Import to GISAF (Only with Authorization) - Click on the import arrow.
