And, they both can write any of the following data: SpatialDataSet, DataSource, ImageLayer, OgcMapLayer, feature collection, feature, geometry, or an array of any combination of these data types. Both of these functions return a promise to add the data to the file.
#Python export kml to csv zip file#
The compressed zip file would contain a text-based file with the spatial data in it. The atlas.io.write function generates a string, while the atlas.io.writeCompressed function generates a compressed zip file. There are two main write functions in the spatial IO module.

In this case, the code uses a CSV file that has spatial data columns.

The demo below shows how to read a delimited file and render it on the map. ProxyService: + '/YourCorsEnabledProxyService.ashx?url=' This snippet of code shows how to pass a proxy service into the read function: //Read a file from a URL or pass in a raw data as a string. The read function appends the file URL to the end of the proxy URL provided. After the first time it fails to access any resource on another domain using CORS it will only request additional files if a proxy service has been provided. The read function will try to access files on another domain using CORS first. You may optionally provide a proxy service for accessing cross domain assets that may not have CORS enabled. See the Pen Load KML Onto Map by Azure Maps on CodePen. Additionally, if the data set has custom icons, those icons need to be loaded to the maps resources before the features are loaded. These overlays must be added on the map separately from the features. KML can contain ground overlays, which will be in the form of an ImageLyaer or OgcMapLayer. The next code demo shows how to read and load KML, or KMZ, to the map. See the Pen Load Spatial Data Simple by Azure Maps on CodePen. The code uses a GPX file pointed to by a URL. The following code shows how to read a spatial data set, and render it on the map using the SimpleDataLayer class. Statistics about the content and processing time of a spatial data set. Property information provided at the document level of a spatial data set. Property nameīounding box of all the data in the data set. The SpatialDataSet not only contains feature information, but it may also include KML ground overlays, processing metrics, and other details as outlined in the following table. It can easily be passed into a DataSource as-is to render its features on a map.
This object extends the GeoJSON FeatureCollection class. The result from the read function is a SpatialDataSet object. Images extracted from KMZ files will be converted to data URIs. Inaccessible image data may load an alternative fallback image or will be removed from the styles. Then, images referenced in KML and GeoRSS files are preloaded to ensure they're accessible. For example, doc.kml, or a file with other valid extension, such as. When reading a compressed file, either as a zip or a KMZ, it will be unzipped and scanned for the first valid file. The read function returns a promise to add the image icons to the map, and processes data asynchronously to minimize impact to the UI thread. The proxy service is used to load resources on domains that aren't CORS enabled. URLs should be hosted on a CORS enabled endpoint, or a proxy service should be provided in the read options. Alternatively, the read function can take in a URL that points to a file in any of these formats. The KMZ file format is a compressed version of KML that can also include assets such as images. This function can also read compressed versions of these formats, as a zip file or a KMZ file. The atlas.io.read function is the main function used to read common spatial data formats such as KML, GPX, GeoRSS, GeoJSON, and CSV files with spatial data. These next sections outline all the different tools for reading and writing spatial data using the Spatial IO module. The table below lists the spatial file formats that are supported for reading and writing operations with the Spatial IO module.
