No databases, just files, and I'm using rgeo 0.3.3 and rgeo-shapefile 0.2.2. I can get the shapefile loaded into rgeo pretty well, but I'm having a hard time taking any Point in the file to a specific Latitude/ Longitude. As a proof-of-concept I'm trying to just get the longitude of the first point in the first entry: Leaflet Provider Demo. Leaflet: Past, Present, Future.

Pulling data from MongoDB and presented using Leaflet.js PaaS: Platform as a Service I write a lot of small applications and scripts to improve my programming skills and to hopefully use in my work. Unfortunately, I cannot share most of them because I don’t have access to a server – almost all of my apps run on a WAMP stack using localhost:8080. Recenlty, I saw a tweet about a service by Red Hat – I remembered them from my Linux club days in college – called OpenShift. What I Want to Build. Albuquerque Registered Historic Places. Demo. Cavis/leafpile. Leaflet-ags/examples/dynamic_tiled.html at master · sanborn/leaflet-ags. RGeo 0.3.20 Documentation. RGeo is a geospatial data library for Ruby.
Summary RGeo is a key component for writing location-aware applications in the Ruby programming language. At its core is an implementation of the industry standard OGC Simple Features Specification, which provides data representations of geometric objects such as points, lines, and polygons, along with a set of geometric analysis operations. This makes it ideal for modeling geolocation data. It also supports a suite of optional add-on modules that provide various geolocation-related services.
Use the core rgeo gem to: Represent spatial and geolocation data objects such as points, lines, and polygons in your Ruby application.Perform standard spatial analysis operations such as finding intersections, creating buffers, and computing lengths and areas.Correctly handle spherical geometry, and compute geographic projections for map display and data analysis.Read and write location data in the WKT and WKB representations used by spatial databases.

Using Leaflet.js with non-geographic imagery - Oliver Marriott. Hey!
The steps roughly required are: Split large image into smaller tiles.Rename tiles to fit naming conventions.Insert JS to convert between pixel coordinates and set the max bounds of the map. For this example we'll assume our image is 1024x6144. Examples: Realtime Click Heatmap. This example shows a realtime heatmap with click data, if you click on the surface to the right it will add the datapoint right after the click.
Click on the heatmap in order to create datapoints! Google. GeoMOOSE users - [Geomoose-users] Layer auto refresh. Seems like the approach would work, but I'm still not sure that GeoMOOSE.refreshLayers API was ever implemented (Duck, please correct me if I am wrong).

Layer control displaying garbage values. Web Safe Colours Diagram with rgb and hex values. What are web-safe colours?
The diagram below illustrates the 216 web-safe, or browser-safe, colours. These are the only colours that can be displayed reliably across all browsers and operating systems running at 8-bit colour depth (i.e. the colours will not dither or band when used to display areas of flat colour). If non-web-safe colours are used for areas of flat colour, unsightly dithering can occur when a page designed for a pc is viewed on a Mac, or when a page designed in Internet Explorer is viewed in Netscape Navigator.
The web-safe palette is based on mathematics, rather than aesthetics, and comprises all colours with red, green and blue decimal values of 0, 51, 102, 153, 204 and 255 ( or 00, 33, 66, 99, CC, FF in hex). Rather than displaying the web-safe colours in terms of hue, saturation or luminance, the diagram displays the colours in a format that allows colour patterns and complementary colour combinations to be more easily identified. Local projections in a world of spherical mercator. Update 2014-02-24: A more thorough and updated version on the topic is The Hitchhiker’s Guide to Tiled Maps.
The premise: you want to use the new and cool open source mapping solutions like Leaflet, TileStache and TileMill. While you love projects like OpenStreetMap, you are in a position where you cannot throw out your old map tiles, that are rendered in some local projection, instead of the the one projection to rule them all, spherical mercator. You need to coerce these tools to use your projection and your tiles. Fortunately, these tools do support local projections, or at least were designed with this support in mind.
Yay! A projection (in cartography) is a way of transforming a location on the earth, typically described by a latitude and longitude, to a flat surface (a map) coordinate, like x and y. Tiling means that we chop up a large (sometimes really, truly, huge) bitmap into smaller more manageable bitmaps that can later be put together to appear as one seamless image again.
