GeoSHPer

GeoSHPer is a JavaScript library for converting shapefile data into GeoJSON. It reads ZIP archives containing .shp, .dbf, and .prj files, parses geographic features and attributes, and supports coordinate transformation using Proj4js. The result is a GeoJSON FeatureCollection, enabling easy integration with web mapping libraries.

WME GeoFile

WME GeoFile is a File Importer that allows you to import various geometry files (supported formats: GeoJSON, KML, WKT, GML, GPX, shapefiles(SHP,SHX,DBF).ZIP) into the Waze Map Editor (WME). The script enhances the mapping utilities offered by WME by overlaying geospatial data directly onto the maps.

Table of Contents

Usage

Once the script is installed and running, it will add a 'GEO' tab to the WME sidebar. You can use this tab to:

  • Import geometry files by selecting them from your computer.
  • Customize how these geometry files are displayed on the map — stroke color, font size, fill opacity, line size/style, label color, label outline color & width, and label position.
  • Edit any loaded layer's style after import by clicking its name in the Loaded Files list to open the Edit Style Dialog, then clicking "Apply Changes" to redraw the layer instantly.
  • Clear all imported layers or selectively remove items.
  • Import Well-Known Text (WKT) directly into the editor via the GEO tab import functionality.
  • Draw state, county, county-sub & zip code boundaries based on the area in focus within WME (U.S. Only).

Enhancements

Built on the original code by Timbones:

  1. User Interface Improvements:

    • Added a user-friendly GEO tab within the WME Scripts sidebar for managing geometry imports and settings.
    • Enhanced styling to form elements (buttons, sliders, labels, etc.) for a better user experience.

  2. Customization Options:

    • Added options for customizing layer properties such as stroke color, font size, fill opacity, line size/style, and label position.
    • Label Color: Choose a custom label text color or toggle "Match stroke" to keep it in sync with the stroke color.
    • Label Outline Color: Choose a custom label outline color (default black) or toggle "Match stroke". Provides contrast so labels remain readable over any background.
    • Label Outline Width: Set a fixed pixel width or toggle "Relative to Font Size" (default ON) to automatically compute the width as font size ÷ 4, scaling proportionally as font size changes.

  3. State / County / County-Sub and ZIP Code Boundary Drawing:

    • Available only if WME is started with the Top Level Country of the U.S. - Data source is US Census Bureau.

  4. "Whats in View" Feature:

    • Introduced a new draggable overlay that displays geographic data visible on the map, including states, counties, towns, and ZIP codes.
    • The overlay updates dynamically to reflect changes in the map view, providing insights into the currently visible areas.
    • Geographical entities are listed in a structured, sorted manner for easy reference.

  5. Layer Management:

    • Added options to clear imported layers individually.
    • Incorporated layers into the WME Geometries section in the WME Map Layers sidebar, allowing for the visibility toggling of each layer independently.
    • Implemented IndexedDB for enhanced performance, enabling efficient data storage and management of larger files compared to standard local storage methods.

  6. Improved File Handling:

    • Streamlined the file import process with improved error handling for unsupported file formats.
    • Automatically converts WKT input to GeoJSON before rendering for easier integration with WME.
    • Supports Multi Line WKT files.
    • Automatically converts GPX input including the <extension> tags to GeoJSON before rendering for easier integration with WME.
    • Automatically converts ESRI Shapefiles in .ZIP format to GeoJSON before rendering for easier integration with WME.

  7. Support for Projection Transformations:

    • Integrated PROJ4js library to facilitate transformations between different coordinate reference systems.
    • Supports a wide array of EPSG codes including:
      • EPSG: 3035, 3414, 4214, 4258, 4267, 4283, 4326, 25832, and series 26901->26923, 27700, 32601->32660, 32701->32760.
    • Automatically handles all transformations from SHP Zip files that contain a .prj file, ensuring accurate mapping and data representation on the WME platform.

  8. Edit Style Dialog:

    • Click any layer name in the Loaded Files list to open a floating, draggable Edit Style popup pre-populated with that layer's current stored values.
    • All style properties can be adjusted: stroke color, font size, label color, outline color, outline width, fill opacity, line size/style/opacity, and label position.
    • Click Apply Changes to redraw the layer on the map instantly — no re-import required. The updated style is persisted to IndexedDB and will reload correctly on the next WME session.
    • Attempting to import a new file while the dialog is open shows a warning; close or cancel the dialog first.

  9. Enhanced Label Management:

    • Improved label handling, including finer control over label positioning and styling.
    • Custom Labels: You can define custom labels using placeholders for dynamic values.

Creating Custom Labels:

  • Enter your custom label using ${attributeName} for dynamic values.
    • Feature Example:
      • Attributes:
        • BridgeNumber: 01995
        • FacilityCarried: U.S. ROUTE 6
        • FeatureCrossed: BIG RIVER
    • Example 1 (explicit new lines formatting): #:${BridgeNumber}\\n${FacilityCarried} over\\n${FeatureCrossed}
    • Example 2 (multi-line formatting): #:${BridgeNumber} ${FacilityCarried} over ${FeatureCrossed}

Expected Output: #:01995 U.S. ROUTE 6 over BIG RIVER
