Cad to gis converter




















At the same time, Cityworks AMS was connected directly to the GIS and allowed the department to stop tracking work in multiple places such as in Excel, Access, and on paper.

This provided the ability to tie work to the particular network feature in the GIS. There was a steep learning curve for everyone in the Utilities Department, but that is expected when you change nearly every work process. Staff learned and adapted to the changes and challenges while continuing to achieve work targets and goals. Some call the new maps "smart maps" because you can click on features and get the details needed, which were not previously available.

Additional benefits include redline tools, map updates available in the field, and new symbology options. Pipe symbology is now driven from the attributes to display pipes by status, pressure zone, or material. Staff are also able to select the layer they need for a particular situation.

Those savings have increased since the assessment due to improved field workflows. If possible create the new file geodatabase on the local hard drive.

Browse to the CAD file on disk and select it as the input. The software automatically creates a feature dataset in the default geodatabase to contain the data, although the name can be changed if desired.

The name cannot contain spaces, although underscores can be used. Instructions are provided below for determining an appropriate reference scale for the data. The features from the CAD file are imported to feature classes in the feature dataset. Alternative instructions for importing the CAD annotation to the geodatabase are provided below. These alternative steps preserve the font used to create the text, as well as the color and size of the original text entities from the CAD file.

Alternative import method Create a new file geodatabase, then right click on the geodatabase, and create a new feature dataset, defining the projection to match the coordinate system in which the CAD data was created.

Importing annotation by this method creates another point feature class, with each point at the anchor point for the annotation string. The annotation string is preserved in the TextString field in the geodatabase feature class. Click OK. The feature types selected are imported to the feature dataset in the geodatabase. To determine an appropriate reference scale for the annotation, open a new, empty map in ArcMap, and draw the CAD annotation.

On the General tab, set the map and display units to the units in which the data was created, for example, feet, meters or other units. Zoom in to the annotation until in the screen display of the annotation is rendered at a suitable size for viewing or printing.

Once the reference scale is set for the new annotation feature class in the geodatabase, it cannot be changed. The reference scale should be set to a map scale which is typical for the data, either for plotting or on-screen display. Open the ArcCatalog window, and navigate to the geodatabase that contains the point, polyline polygon and multipatch features from the CAD file. This will contain the annotation. Give the new annotation feature class a name, and click Next through the subsequent dialogs.

For example, the scale in ArcMap may be Type in the Reference Scale box. In the final dialog where the attribute fields are listed, if you want the attributes from the CAD annotation included in the geodatabase annotation feature class, click the Import button, navigate to the CAD annotation feature class, select it, and click Add. Converting CAD to GIS is a common requirement for enabling digital plan submissions , facilities management projects, and more.

This is because GIS is often used as a central data store that adds helpful spatial context and attributes to your CAD drawings. Run your workflow as needed, or set it up to run in response to an event like when a client submits new data, or on a nightly schedule. FME is great at handling the geometry, text, and other information during this conversion. To fine-tune how you want FME to handle all the details, add specific transformers to your workflow.

You can also filter the data features, say to split lines into different layers or classes based on some value. An important step as you transform the geometry features is to use the GeometryValidator to check for problems, like corrupt geometries, self-intersections, and null values.

The key in this translation is to preserve the CAD labels, text, blocks, dimensions, styles, and symbols by making them attributes in the output GIS dataset.

Use the NearestNeighbor transformer to store labels on the nearest line or polygon. Depending on your requirements, you might want to use an attribute blob to store CAD symbology. Learn more in this webinar. CAD is usually not georeferenced, which means you need to set or reproject the coordinate system during this conversion.

FME has an entire category of transformers for validating the quality of your data. In addition to checking the geometry like we talked about above, you can check the attributes using the AttributeValidator, ensure the data model complies with standards, remove duplicate features, and more.

You can also generate a data validation report.
