Inserting image tiles based on coordinates and scale
The file name of the tiled data from MapWarehouse contains the tile’s insertion point in UTM coordinates. By interpreting the file names you can find: The data type (orthophoto, parcel, contours…) The UTM coordinates of the file’s insertion point The year the data was produced The data provider (FBS, Teranet, TRCA…) The first letters tell […]
Tips to conserve bandwidth usage
There are several options: Turn off the MapCast layer off when panning and zooming. Turn the MapCast layer off when zoomed out to smaller scales beyond 1:10,000. In CAD, choose the resample raster option to crop the imagery to your view so excess imagery will not draw when you zoom out. In ArcMAP, choose the […]
How is bandwidth measured?
Users on MapCast with WMS compliant software can request an image that will match the screen resolution or scale of the software’s window. The request is sent through the Internet to the FBS servers where the image is generated and then returned to the user to be displayed in the software’s window. This action will […]
Volume discounts for large orders
Our subscription services, MapCast and VuMAP, both offer volume discounts when you buy a multi-user plan or buy multiple subscriptions at once. MapCast subscribers will find the pricing quoted at the bottom of the page based on the number of data access users added their plan as they build their custom subscriptions. VuMAP subscribers who […]
Is the date and time of the photo included?
The mosaics on MapCast and VuMAP, as well as the photo tiles on MapWarehouse are made up of several photos stitched together. To locate the date and time for a tile, it is necessary to look up the flight plan to find the original photo most closely centered on the particular tile. The flight plan […]
How to merge tiled contours into continuous lines
Here’s one way: Copy the line work from one file, open the file for the adjacent tile and use the command “paste to original coordinates” to have them together in one DWG. Use the command PEDIT (polyline edit). Select M (multiple), and choose all the linework from both tiles and hit enter. You will be […]
The property lines don’t match the image below.
The orthophoto are generally spatially accurate to double the resolution value. Simply put, if a photo has resolution of 20cm, any point on the photo will be accurate within 40 cm of its true location. For the parcel data, different Land Registry Offices in Ontario were originally drawn to different standards and then later integrated […]
The flood plain mapping I bought was 0 kb.
Floodplain mapping is available on an “as-is” basis with no routine update schedule. Sections of floodplain mapping will be updated from time to time as needed when major storm events cause flooding that exceed predictions. While a section of floodplain is being updated, the map status will be temporarily listed as “DRAFT” in the info […]
How can I convert the geometry of adjacent parcel tiles from polylines to polygons?
Polygons would not be a good representation of the data in this case because the geometry of the parcels is clipped to the boundary of the tiles, so the area, perimeter, and parcel boundaries of the properties on the edge of the tile would be misleading. A closed polyline indicates the entire property is included […]
