ENGO 651 - Advanced Geospatial Topics

This website is an assignment for Advanced Geospatial Topics (ENGO 651) by group 6. We created a web mapping application for building permits in Calgary, Canada, which is taken from the Open Calgary API dataset. Users can find all building permits on the map by selecting the issue date range they like. Moreover, some useful information, such as contractor name and community name, of any building permit exists on the pop-up content of the marker that represents the specific building permit. To make the map visually appealing, we handled the problem of overlapping markers and made a cluster of the neighboring markers on the map.

For Lab 4, we have added a mapbox layer showing the locations of traffic incidents in Calgary, from csv dataset found on Open Calgary Data website. We created a layer on Mapbox layer and imported the data from the outlet mentioned above and added some personal touch to the map. This Geoweb Application will now be able to display not just building permits in Calgary when users search for it, it will also be able to display locations of traffic incidences in Calgary. All marker and map styles were done in Mapbox.
