  • Photos: Photos from the site could help us figure out the features in the site to present and callout them correctly. Sometimes, we can use Google Earth to view the site nearby streets. However, this way can’t be used for the site located far away from Streets or the street is private or restricted. In some cases, the data from Google Earth Street View is old of date. Therefore, photos from the site are still necessary for us to perform the topographic survey drawing.

After receiving all necessary information, we will use Civil 3D to import the point file, arrange the points in appropriate point style and label styles. We can perform the linework process to generate linework or draw them manually depending on how the point data is. We will check the survey info with as-built information on the local website, portlandmaps.com is an example.

Next, we will build the existing surface form a point group which just show ground points. The surface need to be modified so that it reflects the existing surface. We ever met a site on a hill with very steep slopes with many retaining wall. We had to assume additional points to make the surface makes sense. Building existing surface is one of most challenging tasks that isn’t for new bees to outsource Topographic Survey Drafting Services.
Next, we need to label the existing contours and finalize the topographic survey drawing.
Finally, the latest item in any process at EPO that is Quality Control. Actually, we have Quality Control during each activity but final check is critical. We often plot the Topographic Survey Map and double check in papaer to see if any mistakes missed.
