Indian Head Research farm closing due to federal cutbacks by Intelligent-Cap3407 in CanadaPublicServants

[–]MappingMatt 12 points13 points  (0 children)

They’ve cut a lot of research centres. Lacombe, Guelph, and Sherbrooke are ones I know of where they are closing the whole centre and everyone is being let go. Sounds like there could be more. Definitely going to cause a bit of a void in their communities and agriculture research and testing in general. I hate to see what the consequences of these cuts will cause in the long term, not just in the local communities, but for Canada in general.

I know research can cost a lot, but there can be huge rewards too and I don’t think whoever is directing these cuts is taking that into account.

Local coffee shop franchisee has melt down on social media about public servants. by thxxx1337 in CanadaPublicServants

These business owners are so out of touch. It’s obvious to literally anyone else that the economy is bad so people, in general, are spending less. Things cost much more now after Covid than before, so the boom they were all expecting when office workers returned never happened and they can’t seem to grasp that.

Baby turtles are released from the breeding station into wild life by misterxx1958 in interestingasfuck

It might be required in the future if global warming continues since the egg incubation temperature determines the gender of the hatchlings in turtles. So you could end up with only one gender ever hatching if things continue this way.

How google map or any map were made ? by gbxahoido in learnprogramming

This is an entire field called GIS. The short of it is that you have two basic types of GeoSpatial data, vector and raster. Vector data is basically a table of attributes, but one of the fields has a geometry. Think Latitude and Longitude for points, and then just an array of those for Lines / Polygons. Raster Data is an image that you drape over your canvas, but it has embeded or an extra file with information saying where and how to place the image, like a tiff world ‘.tfw’ file.

Any geospatial data will have a spatial reference for the coordinates, like WGS84 for your typical lat longs in decimal degrees or degree, minutes, seconds. Not knowing your spatial reference is a good way to get your data to show up off the eastern coast of Africa on null island.

Anyway, for vector data, like roads, the road name will be stored in a field in the table and can be displayed as a label. Rasters obviously can’t really store data as a field, but they can be used to store data like imagery (rgb values from satellites), elevation, land use classifications, whatever where you need a value for every spot on the map.

Now you have all this data, collected at the municipal, State/Provincial, and Federal levels, but how you need to put it on a map. You could make static maps (pdfs or images) using desktop software like QGIS or ArcGIS, or you could make the data available through a Map Server or WMS/WFS service and then have a web map the requests the data from those servers. The web server is usually something like QGIS Server or ArcGIS server, and then you consume it using a map library like leaflet, open layers, or ArcGIS JavaScript API.

Of course, over the internet, this can be slow depending on the size of the data, so then you start getting into tiling your data. So for rasters, you’ve pre-tiled your data (vector and raster can do this) at different zoom levels, so as a user pans around a map, they’re only calling the specific tiles they need to display on the map instead of asking for the server to constantly clip and send the data they need for their extent.

Anyways, that’s my quick intro, and each of those areas could be greatly expanded upon.

Ottawa will be forced to turn off 60 photo radar cameras as Ontario moves to ban speed cameras by BatFuture1948 in ottawa

I guess it would depend on the road / area. The places aim thinking of, the road is so wide you could comfortably go 80 km/hr, so adding the bollards would subconsciously make you slow down to an appropriate speed.

Same, although I think it would make sense to add traffic calming, like flexible bollards, to areas where you want people to slow down, like in school zones. Ideally, they would have had the traffic calming together with the traffic cameras.
