MWS (MapWindow Session)

GISBox is a one-stop 3D GIS data editing, conversion and publishing platform that supports editing in multiple GIS formats such as OSGB/GEOTIFF/RVT, converting to 3DTiles/Terrain and publishing.

Introduction

MWS (MapWindow Session) is a session file format used by MapWindow GIS software. MWS files contain information about geospatial data, layer settings, symbolization, and map views. It allows users to save and load GIS projects to restore the state and configuration of maps in different work sessions. MWS files can contain vector data, raster data, styles, and symbol settings, providing GIS users with a convenient way to manage and share geospatial information.

Data Format

Geospatial data:

Vector data: Geometric figures such as points, lines, and surfaces, which represent specific geographic features on the map.
Raster data: Such as satellite images, topographic maps, etc., which provide background and detailed information for the map.

Layer settings:

Layer information: including the name, type, data source, etc. of each layer.
Layer order: defines the order in which layers are superimposed on the map, affecting the display effect of the map.
Layer visibility: controls whether the layer is displayed on the map.

Symbolization and style:

Symbol settings: defines the symbol style of each geographic feature on the map, such as point symbols, line symbols, and surface symbols.
Color and transparency: sets the color and transparency of map elements to improve the visualization of the map.

Map view:

View range: defines the display range of the map, that is, the map boundaries and zoom level.
Center point: sets the center point of the map, usually used to locate a specific geographic area.

Other configuration information:

Annotation settings: such as annotation font, size, color, etc.
Scale and grid lines: Provide map scale information and grid line settings.
Projection and coordinate system: Define the map projection method and coordinate system to ensure the accuracy and consistency of the map.

Pros

1. Convenient project management: MWS files can contain vector data, raster data, styles and symbol settings, etc., providing GIS users with a convenient way to manage and organize map projects. Users can easily save and load map projects without reconfiguring complex map settings.

2. Promote collaboration and sharing: MWS files support sharing functions, allowing multiple users to easily share and collaborate on map projects. This helps improve work efficiency, reduce duplication of work, and promote communication and cooperation between teams.

3. Simplify workflow: MWS files simplify map display and workflow management by integrating all relevant information of map projects. Users can access and use the required map data faster and improve work efficiency.

Cons

1. Software Dependency: MWS files are specific to MapWindow GIS software, so MapWindow GIS needs to be installed and used to open and edit these files. This limits the scope of use of MWS files and may not be very user-friendly to other GIS software.

2. Compatibility Limitations: Since MWS files are specific to MapWindow GIS, they may not be directly compatible with other GIS software. This may result in additional conversion steps or tools being required in some cases to open or edit MWS files in other software.

**3. Potential Data Security Risks: **If MWS files contain sensitive or confidential information and appropriate security measures are not taken to protect it, then this information may be at risk of being leaked. Therefore, when using MWS files, you need to ensure that appropriate security measures are taken to protect sensitive data.
