Geographic data can also be retrieved from SQL database tables using DataLayer.SQL see for more information.With Google Maps Easy Plugin you have an incredible ability to display different geographic information with KML files in your Google Map. Software tools, discussed in Map Polygons, are available for converting shapefiles into GPX or KML data files. Because of their public nature, this data is often freely available on the Internet.ĭata is also widely available in shapefiles, a popular geospatial vector format for Special datalayers are provided in Logi Info to read these files. GPX or KML files, which are GIS industry-standard XML data files. For use with Logi elements, these typically come from Multiple segments are used to draw a continuous line. Plotted using sets of latitude and longitude points that describe line segments. Other use-case examples include subway maps, traffic density indicators, and pipeline route mapping, to name but a few. In the example above, they've been configured so that when they're clicked, an information panel is displayed containing more detailed information about the immediate location. Polylines can be configured with Map Marker Info pop-ups and can be related to other data. The line above has been configured to be semi-transparent, so that geographic features can be seen through it. Polyline color, width, and transparency level are all configurable and can be set from data values. The map above uses polylines to show a route from the Orsay Museum in Paris to the Louvre Museum. Map Polylines, plotted onto the map, are overlays that are drawn, and can be color-coded, based on data The element works in the same way for either mapping system. However, with the introduction of Leaflet maps, the "Google" part of the name was dropped. Prior to v12.5, the element being discussed in this topic was called "Google Map Polylines". If you haven't already, you should first read Leaflet Maps or Google Maps, which provide general information. The following topics discuss the use of Map Polylines: They're often used to depict a route from one place to another. In Logi Info, this allows you to overlay solid or semi-transparent, color-coded lines on a map, based on data. If you've used Google or Leaflet maps to provide geographic mapping solutions in your Logi application, you can take advantage of another advanced feature, Map Polylines.
