DXF

Endpoint​

POST https://api.geoflip.io/v1/transform/dxf

Payload Example (Multipart Form)​

To submit a DXF file, the file must be provided in a multi-part form submission and for you must provide an input_crs in your config.

<html>
    <input type="file" id="fileInput" accept=".dxf" />
    <button id="uploadButton">Upload and Convert DXF</button>
    <a id="downloadLink" style="display:none;">Download Converted File</a>

    <script>
        document.getElementById('uploadButton').addEventListener('click', () => {
            const selectedFile = document.getElementById('fileInput').files[0];
            const formData = new FormData();
            formData.append('file', selectedFile);  // DXF file

            const config = {
                output_format: "geojson",
                input_crs: "EPSG:4326",  // Required for DXF
                transformations: [
                    {
                        type: "buffer",
                        distance: 100,
                        units: "meters"
                    }
                ]
            };

            formData.append('config', JSON.stringify(config));

            axios.post('https://api.geoflip.io/v1/transform/dxf', formData, {
                headers: {
                    'Content-Type': 'multipart/form-data',
                    "apiKey": "YOUR_API_KEY"
                }
            })
            .then(response => {
                console.log("File converted successfully:", response.data);
            })
            .catch(error => {
                console.error("Error converting file:", error);
            });
        });

Explanation​

  • API Key: Your Geoflip API key must be provided in the request headers. You can create an API key here.

  • Input CRS: The input_crs must be provided in the config for DXF files since they do not contain CRS information inherently. This ensures that the spatial data can be correctly transformed and interpreted.

  • Multipart Submission: DXF files must be provided in the file part of the multipart form.

  • Config Component: The config component is where you define output details (output_format, output_crs) and specify transformations.

  • Transformations: Transformations can be specified in the request payload using the transformations parameter. These transformations allow operations like buffering and more complex spatial manipulation. Read more about available geoflip transformations here.

  • Output Format: The output_format can be one of dxf, shp, geojson, or geopackage.

  • Output CRS: The output_crs can be any valid EPSG code, such as EPSG:4326.

Note that requesting a binary file output (e.g., dxf, shp, geopackage) will return a blob in the response, while requesting a geojson output will return the required GeoJSON in the response body.

Key Considerations​

  • DXF is a CAD file format used for vector data such as lines, points, and polygons.

  • Users must specify the CRS (input_crs) since DXF files lack this information, which is critical for accurate spatial transformations.

  • Multipart form submission ensures that the binary DXF file and its configurations are transmitted correctly.
