If you want to go open source, you could start with this Introduction to Geoserver from last year's FOSS4G: http://workshops.opengeo.org/geoserver-intro/ Tools involved are usually Geoserver, PostGIS and OpenLayers. Start up costs is your work time plus hosting. It's hard to estimate time to deployment without knowing your use cases. Update: If you are ...

I'd like to suggest two books. The first one is Learn to Think Spatially from the National Academies Press. It is actually about the nature and functions of spatial thinking and shows how spatial thinking can be supported across the K-12 curriculum through the development of appropriate support systems like GIS but it should give you an idea on how to ...

I love your enthusiasm and running your own GIS Consultancy can be very rewarding. I worked my way up to running a commercial GIS Unit for a very large environmental research and consultancy service, plus lead GIS teams in other organisations before going freelance. This experience gave me a very good idea of what running a business would involve, who my ...

To be honest the time frame you mentioned for the migration sounds really tight, especially if you want to research, test, evaluate and deploy! We have recently migrated from using ArcGIS as our desktop client to QGIS. While everything you have mentioned sounds possible the biggest issue I have found is managing the storage of Raster datasets, but like Nick ...

1) Analyse the areas outlined with the polygons and added buffers to some of them. Buffers are supported. For further help, we'd need to know what "analyse the areas" means. 2) Answer questions like: Does this kind of fish (represented by a layer of points) always occur near a certain rock type (represented by polygons or points). You can check if ...

I also just attended a conference where they presented the OpenGeo Suite, which is a stack of OpenLayers, GeoServer, GeoExt & PostGIS. They offer both the "Enterprise Edition" (paid for version with support) or the "Community Edition" (free) versions. Another package that was demonstrated at the conference was GeoMoose, which is a stack of MapServer ...

If you want to simply prototype something for a viability study to show your boss, which is what I had to do a year or so ago, then for the backend I'd recommend Geoserver because of its user-friendly web interface, backed by some simple shapefiles. For the frontend, OpenLayers is a fantastic choice with lots of samples on the website. I'm not a ...

This illustration stuck with me, and helps me remember at the most basic level what precision vs. accuracy is.This is the source of the image, also containing a little more context. In general, Precision is the how close your grouping of measurements are. Accuracy is how close your measurement is to the actual measurement in the real world. Blah238 is ...

Change detection is a common operation/module in remote sensing packages like ENVI or Orfeo toolbox. It usually involves raster data (satellite images for example). How is the comparison done? With what tools? I feel that the description is not complete. Or something is missing. Change detection is done by comparing two raster images that were taken ...

Penn State has an Open Web Mapping class. It should be enough to teach you how web mapping works, and also the technologies involved. Most, if not all, of the tools used in the class are free so you cost shouldn't be a problem. Here's the TOC: Lesson 0: Orientation Lesson 1: Introduction to Open Web Mapping Lesson 2: Web Map Servers (WMS) ...

It looks like you have gotten the Open Source answers in the question above. If your company has the budget, ESRI can be a very good option. To clarify, the webmapping APIs in and of themselves are free to use, however the backend ArcGIS Server and SDE will cost you money. Additioanlly, desktop software will be needed to create map services to be used in ...

Personally, for the cliff's notes I find the ESRI ArcGIS desktop software help system useful, and and also the ESRI book Understanding Map Projections, its first 30 pages are not unlike a short textbook, followed by ~70 pages of appendix on individual projections, their uses, strengths, weaknesses, etc. From these, you'll quickly understand all the pieces ...

There are so many options out there and many great answers already. Two of my favorite choices that haven't already been listed here are CartoDB and MapBox. Both of these provide web based hosting and visualization of data and some very fancy tools with prices starting at FREE. You'll benefit from having desktop software to get your data setup. ArcMap and ...

The reference (in the US, at least) is John Snyder's Map Projections--A Working Manual. The entire monograph is available as a Google book. Introductory sections give the theory. The theory is accessible to someone with a working knowledge of multivariate calculus. Emphasis is on documenting formulas, primarily series expansions needed for subsequent ...

Things that comes to mind from an IT perspective are: hardware, servers (OS/Database), backup, offsite data storage, business continuity plan in the event of power outage/emergency (UPS power supply), do you want staff to work remotely (VPN), licensing, local laws around running a business, building lease...the list goes on. It all depends on what you will ...

I don't think you will find many tools for change detection on vector data (like shapefiles) because its a trivial problem - just walk the points, and tell me if they are the same. Change detection is more typical for raster images (e.g. SAR images, or visual/IR images), where the problem is detecting what has changed from one satellite pass to the next, or ...

I wrote practical GIS Analysis over a decade ago primarily based on workstation arc/info. If you visit my Intro to GIS website http://nrm.salrm.uaf.edu/~dverbyla/nrm338 there are many spatial problems you could work on (Thursday class, each week has pdf of 3 to 4 spatial problems and a pdf of the conceptual solutions). Hope that helps. Dave Verbyla

I worked as a GIS analyst in the celluar telecommunications industry for a short while. Most of my tasks centered around working with coverage data, i.e. making coverage maps. I also did a lot of analysis with Census data, determining how many people we covered, what services they were covered with, and how many people lived in areas with "good" coverage. ...

I have done several projects in this regard, but at the end they always ended up being custom solutions that basically separated the problem in grids did the processing in each individual node and copied the result to a temp table / data store merged all the solutions to a single result table and optionally handled boundary conditions. Handling boundary ...

I'd suggest starting from http://www.w3.org/Mobile/posdep/GMLIntroduction.html. If you're planning to work with application schemes in INSPIRE, you'll also need a thorough understanding of XML and XSLT (Extensible Stylesheet Language Transformations). I think the task doesn't require in-depth understanding of UML. You'll have to be able to read it. Anyway, ...

The QGIS project site's How Do I Do That in QGIS should be a good starting point. It is intended to show how to perform basic GIS operations in QGIS in the most straightforward way. It is modelled after “How do I do that in ArcGIS/Manifold?: illustrating classic GIS tasks”. That document illustrated a selection of tasks which were thought to be ...

I too have recently started the web mapping journey after many years more on the database side of things. What really helped me was learning basic programming principles, using MapBasic for MapInfo (or I am assuming Python for the esri crowd) really helped me understand how computers "think". From there CodeAcademy was a godsend. Its a really fun and ...

Start building a portfolio, it can be worth more than your resume and education credits. Every time you produce something you are proud of -- a map, a geoprocessing model, a paper, a mashup, a complex analysis -- save a representive sample in hardcopy as well as digital. Send this in along with your resume. If you don't have things you're proud of to stick ...
