Here's a little QGIS python function that implements this. It requires the rasterlang plugin (the repository has to be added to QGIS manually). It expects three mandatory parameters: The points layer, a raster layer (to determine the size and resolution of the output), and a filename for the output layer. You can also provide an optional argument to ...

It actually seems very reasonable from a price perspective. I would specify it meets XXXX standard of accuracy and I would specify the file be in las 1.2 (or another spec as desired). Specify the classes you require and the RMSEz that is acceptable (often just vertical in lidar). 7 points per m is high. I find this document very useful. It spells out what ...

The short version is - Seek professional help. The longer version: You appear to have some vague knowledge of what you want to do but certainly don't have the specifics. What you have here is an entire Corporate GIS project and you should go through the Project Management process for it. What are your requirements? What do you need to connect to what? Who ...

There are a number of places where footprints can come in very handy Public Sector: Taxation: As @Mapperz said, taxation is one area. The percentage of property that is built on is sometimes used as a tax criterion. Planning: Knowing where structures already exist on property can help in the planning process due to applied setbacks and minimum distances ...

You could try Flowmap. It is specially designed to analyse flow patterns. You can find it here: http://flowmap.geog.uu.nl/

The complexity of an online map is widely dependent on several things; first being what api/platform you want to use (CartoDB, ArcGIS Online, Google Maps, etc...). What API/platform is best to use will be at least partially dependent on several other factors though, such as what licensing restrictions you can work within (ex: most of Google's api's ...

DGIS From Wikipedia: Distributed GIS concerns itself with GI Systems that do not have all of the system components in the same physical location. This could be the processing, the database, the rendering or the user interface. Examples of distributed systems are web-based GIS, Mobile GIS, Corporate GIS and GRID computing. and well, Web GIS ...

I would strongly recommend Maptitude as a geospatial software package to meet your spatial analysis needs. I have been a user of the software for about 3 years now, as the software is quite affordable compares to MapInfo and ESRI Business Analyst Online. The software is aimed at the business person who needs to do site selection work, demographic analysis, ...

It is usually more meaningful to compare quotes from different providers for the same situation/contract. However, I tried to make a rough comparison with the work of Hummel et al. (2011). OP. 30k CAD / (70 Km² x 247.105 acres/Km²) = $1.73 CAD/acre or $1.92 USD/acre. (Considering a ratio of CAD/USD = 1.11 in Oct/2014). Hummel et al. (2011). They report ...

In addition to the points in the other answers, make sure that you have well defined control points and callibration. You will get the most use out of LiDAR that you can compare from collection to collection. If a company will not provide you with this data, it is best to pay a little more. I have come into a project to find that there is no way to compare ...

You can get data on specific types of features such as libraries (not necessarly all of them, but at least a good sample) from Open Street Map. In the case of library, you're looking for things with an amenity tag of library. You can download the OSM data in a lot of ways, but you may find the Overpass API useful. Here is a very simple query you can use: ...

Select heatmap as layer rendering style and set Weight points by to the attribute 'price'. Than play around with the values for radius and maximum value to get a nice looking heatmap. On the picture, I duplicated the layer to include the points with their price-value in the label that you can see how the heatmap renders depending on the density of the points ...

As graduate of COGS, I would say that you shouldn't really limit yourself to staying and working in either of those Provinces after you're done your studies. Each school offers a program that is marketable really anywhere when you're done! With that said, there were many jobs in Nova Scotia that were offered to prospective COGS grads, and I think a lot of ...

Hey welcome to Canada mate! I can't say I have specific knowledge here, but I'd say you're probably right with BC's job market being a bit more promising than Nova Scotia's. Here's a real quick breakdown of some provincial economic indicators from Statistics Canada's most recent data (not specific to the GIS industry but gives you an idea of where they're ...

As others have noted, the investment of time really depends on what you want your map to do. A complex, well-designed tool will require a similarly complex back end. The good news is that most of the available tools are highly scalable, meaning you can start for simple, free (or very cheap) optional and build up in the future. If you have no background in ...

maxcovr package in R: https://github.com/njtierney/maxcovr. This package implements the maximal coverage location problem model and supports a range of solvers (e.g. glpk and lpSolve). It is not in a GIS environment. Location-allocation analysis in ArcMap (though not open-source):http://desktop.arcgis.com/en/arcmap/latest/extensions/network-analyst/location-...

You can use google places APIs , the volume of requests for the free version have a limit. The following example is a search request for places of type 'restaurant' within a 500m radius of a point in Sydney, Australia https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670522,151.1957362&radius=500&type=restaurant&name=...

I recommend either using the Factual APIs: api.v3.factual.com/t/places?filters={"$and":[{"region":"oh"},{"country":"us"},{"name":{"$bw":"McDonald's"},"category_ids":{"$includes":338}}]}&limit=50&offset=450 Or contacting them and asking them for a download. For a preview of the data, see here.

Definitely take a look at this: https://rpubs.com/MichalisPavlis/huff_model and the R library hufftools, which also shows exactly how to download and use a street network for an entire country. The Pavlis Dolega and Singleton paper may also be helpful in thinking about the retail "attractor" question.
