CAN I GET THE LINEWORK IN DXF FORMAT?
Our DWG files will work for most versions, however it can occasionally cause issues across different platforms. Thankfully, all versions of AutoCAD support the DXF file format. If you would like your linework delivered in a DXF format, just let us know and we can send you one. When opening or importing files into AutoCAD, just make sure that under the “Files of Type” option at the bottom of the “select file” dialog box is set to “DXF”.
WHAT LAYERS DO YOU USE TO MARK FEATURES?
We use highly descriptive layers designed to map cleanly with as many different layouts as possible. Our layers are designed to be detailed enough for nearly all typical projects, and descriptive enough to make sense. For more detail, see our Aerotas CAD Layers page.
WHAT SOFTWARE DOES YOUR FILES WORK WITH?
Our linework is delivered as a DWG and can be opened with most CAD programs, including Civil3D or Carlson Survey. This file format also works with most GIS softwares, including Esri ArcGIS and QGIS.
HOW ACCURATE IS THE DATA?
Final accuracy depends on numerous factors, and the only real way to know the final accuracy of a project is to use checkpoints. Aerotas will attempt to estimate the accuracy of each project during processing, however checkpoints are the only true method to know accuracy. When measuring accuracy, Aerotas uses the ASPRS Positional Accuracy Standards. If you would like to integrate checkpoints and accuracy measurements into your project, let us know in the messages section when requesting a quote or uploading your project data.
