Now switch to the Move Selected tool and drag to the new location. Click once with the select tool to select the shape, and then drag a selection rectangle over the node you want to move. If you need to make changes to shapes, it’s possible to do so. You can then delete the routes and waypoints. Once you’ve got everything in place, select the routes and click Convert to Shape on the Tools menu. You can move nodes to a new position by selecting the waypoint at that node and using the Move Selected tool to move it to a new position. If this isn’t what you want, hold SHIFT to override this. Linear routes, tracks, and shapes have a marker (orange triangle) which you can move along the track by clicking. A line will be drawn from the symbol to the text label. So if you are drawing agricultural fields, and put waypoints at all of the field boundaries, as you use the route tool to “connect the dots” you’ll get routes that align perfectly with the adjacent fields.Īs you begin to draw a new route, ExpertGPS might show a + cursor, meaning that is going to extend an existing route. You can also create a 'callout' text label some distance away from the point symbol by right-clicking on the map where you want the text and clicking Place Label Here. This is because the route tool automatically snaps to waypoints as you draw. If they have straight sides (not curved like a river centerline), it might be easiest to draw them using the route tool, and then convert the routes to shapes after. There are a couple techniques you can use if you are drawing filled objects that need to mesh right up against each other. Deleting the shape and re-drawing it is a pain. I could not find a way to ‘grab’ the node and move it to the correct location (feature request). I also had problems when I placed a node off location. I think I have that issue resolved by assigning each land use type to a different layer. I had to leave a gap to keep things from getting messy. I had problems when I tried to append a particular shape of one land use to another shape of a different land use. There were some performance issues with the first release of the product, which have been resolved since migrating to Aurora RDS as the database since it provides a more efficient solution to deal with real-time, concurrent queries at scale.My application requires that I measure the areas of various land use types within a given project area. The location-based search function works on more than 12 GB of spatial data, providing results in real-time. This functionality is implemented using spatial queries provided by PostGIS, which is a spatial database extension for PostgreSQL. Township Canada also provides location-based search where users can drop a pin on the map and get the associated legal land description, geographical coordinates, and postal address in return. In Township Canada, the search function works on more than 16 millions records and provides results in real-time. Full-text search is a resource-intensive operation that runs on the database side. One of the features that Township Canada provides is a Google like search interface - it gives users real-time recommendation as they type in their search term. I even shared a link with a few friends of mine and I got so much love from them :) Then I realized that this tool might be useful to other people who are dealing with legal land descriptions in their daily routine, so I decided to further develop its functionality and release it as a product. So I built a simple web app back in Summer of 2017, as a side-project, and started using it.

The problem I had when I first started in the energy industry was how to easily convert the legal land descriptions into geographical coordinates and map them - I couldn't find an easy-to-use tool at the time. Now, many industries such as oil & gas and agriculture use legal land descriptions to identify their assets like wells, facilities, and land parcels. Legal land descriptions are based on survey grid networks that divide the country into equal-sized parcels of land. What is a legal land description? Any parcel of land in Canada can be located by its legal land description. Our legal description mapping tool uses natural language processing (NLP) and machine learning (ML) to automatically detect and map legal descriptions, bearings, and distances based on original deeds, leases, and more. I made a web app called Township Canada ( ), it's a simple tool that allows for searching, converting, and mapping Canadian legal land descriptions.
