Field Description
Simple Id Not editable. After saving the feature form the feature gets automatically a simple id.
Project Project the feature belongs to.
Name Name of the feature. Use a descriptive one for better handling and usability.
Description Any description relating to the feature.
Minimum scale Minimum map scale for displaying the feature in the client.
Maximum scale Maximum map scale for displaying the feature in the client.
FeatureLoader
  • Cached: The feature class is published in advance and cached on the server. Caching increases Web performance. Tiles that have already been loaded onto the client can be used again locally and offline.
  • Live: The feature class is created on-the-fly when it is requested by the client. Live published data is always the most up-to-date. The map will be newly created for every new map view.
  • Caching on Demand: This is a combination of live-loading and caching. Whenever the client changes the map view, it sends a request to the server and looks for any change in tiles that should be loaded. If there are new ones, the tiles will be generated at once and downloaded - and will be ready to use for other clients.
Output Type Data type for the client to obtain all feature information.
  • Jpeg: Output type for raster feature classes. Images containing many colors (true-color graphics; 24 bit) - such as aerial or satellite photos - are best published in .jpg format. Note that JPEG may compress images, which can lead to a loss of contrast and image quality. The compression ratio or degree of loss can be set with the parameter Raster Quality. The initial raster data is best saved as .ecw files or RGB-colored .tiff files.
  • Png: Output type for raster feature classes. Photos with few colors or gray levels (£ 256; 8bit) - such as ground or town maps - are best published in .png format. This format compresses without loss and supports transparency and color index tables. The file size depends essentially on whether the image contains large, homogeneous areas of color, or whether the pattern of colors changes often from area to area. The initial data is best saved as indexed tiff files.
Rows Number of rows for tiles during publishing process. Width and height of the tiles are automatically calculated in meters.
Blue.pngOnly active when FeatureLoader is set to Cache or CachingOnDemand.


Columns Number of columns for tiles during publishing process. Width and height of the tiles are automatically calculated in meters.
Blue.pngOnly active when FeatureLoader is set to Cache or CachingOnDemand.


Timestamp Shows the date of the last date/time the feature was published. The value "0" indicates that the feature has not yet been published.

Field Description
Coordinate system If the feature has an other coordinate system than the project, you change it here. You can also add a coordinate system by clicking on the Add cs.png button. You will forwarded to the same modal form as you adding a coordinate system for your project.
Entity Titel of the layer.
Url You have to paste your valid WMS Url into this field.
Ini-Path Optionally the path to an INI file can be set here.
Connect Connection parameters to the data source of the feature class.
Opacity Transparency of a feature, usually defined by its alpha channel. Use values between 0 and 1. Value 1 = default and means no transparency.
Map resolution Specifies the tile size in pixels (number of pixels required down the longer tile side, no decimals!).


Blue.pngMap resolution can be extracted from the excel sheets above.


Raster quality[1][2] Compression ratio for .jpeg files; file size decreases accordingly.
Blue.pngRaster quality is only available for Type is Raster and/or Output type is Jpeg for raster/vector data.
