TileMill: Open Source Mapping Now for Windows

TileMill is built on open source libraries (Mapnik, node.js, backbone.js,express and CodeMirror) and uses CSS styling with its map styling language Carto to render beautiful online maps. For an idea of what you can do with TileMill, the Chicago Tribune demonstrated some of its capabilities in its Making Maps series using PostGIS, Mapnik, TileMill, and Google Maps. Demos of TileMill in action can also be viewed on MapBox’s Maps page.

TileMill can now be used natively in Windows with the latest release. The release of TileMill 0.9.0 also includes a new plugin system: “TileMill UI can now be extended and modified using standalone, JavaScript plugins.” The new release also includes many fixes and updates including shipping with a desktop app client instead of requiring a browser.

TileMill has also released a crash courseto help new users walk through using the open source application. The course reviews:, Importing a basic spreadsheet, Styling a basic point map, Adding tooltips and legends, and Exporting maps and sharing them on the web.

MapNimbus - Online Mapping Portal

MapNimbus is an online mapping portal designed to deliver information to citizens in an easy-to-use interface. Web Mapping Application by GeoTechGroup

CRIME MAPPING

MapNimbus boasts a familiar and intuitive interface that is easy-to-use. MapNimbus allows the user to search by address or agency to view crimes in their area. The user can narrow the scope of the search by using a pre-defined buffer. The crimes can be narrowed down even further by specifying a specific date range that you wish to view. To view more information about a specific crime, just click the icon and a map tip will display relevant information about the crime. Online crime mapping is made easier with MapNimbus.

SEX OFFENDERS 

MapNimbus allows the user to view sex offender data for their area. This allows you to keep the public informed of any registered sex offenders residing near their home, work, daycare, school, parks, public library, etc. The user can search for sex offenders near an address. You can click on the sex offender icon and view information about the offender on the mapping interface. MapNimbus also allows the user to click a link and visit the state's sex offender site directly for more detailed information.

RESTAURANT GRADES, CODE ENFORCEMENT, OCCUPATIONAL LICENSING, BUILDING PERMITS, TATTOO PARLORS, ADULT CARE FACILITIES, CHILD CARE FACILITIES, LODGING, POOLS AND SPAS, AND NURSING AND REST HOMES 

MapNimbus informs the public of relevant and important information. When in need of restaurant sanitation grades, lodging grades, child care facility grades, and more look no further than MapNimbus! The easy-to-use interface allows the user to seach by address or pan and zoom the map to the desired location. You can view the inspection date, score and letter grade for each restaurant or view information about building permits in your area. MapNimbus also displays historical grades as well as the current grade for the restaurant. You can sign up for automatic email notification to be notified when sanitation grades change for a user-specified area. MapNimbus allows the user to view a wide array of information about their community. MapNimbus helps you keep citizens informed!

STATISTICS AND REPORTING 

Not only can users view crimes and restaurant data for their area, they can also use powerful statistic and reporting tools to view a summary of the occurrences in their area. The reporting tools show a summary of what is being viewed on the mapping interface, whether it be crimes, restaurant grades, or other data. The user can also view a summary of the entire agency.You can choose to view a pie chart, bar chart, or tabular data. As you pan and zoom the map, the charts automatically update to reflect what you are viewing on the map. Once you have the sample of data that you desire, you have the option to print the information.

EMAIL NOTIFICATION 

MapNimbus allows users to sign up to receive automatic email notifications for changes in their area. They can receive an email when a crime has occurred within a specified distance of the address they choose or when a restaurant grade changes within the area they specify. This allows the public to automatically be notified of important information in their area!

Frozen Planet

Frozen Planet: Explore the Polar Regions features an interactive display through which you can view the history of polar exploration and the science of the polar regions. The interactive display is created through the use of the Google Earth browser plug-in and a timeline. You can click along the timeline to see and read placemarks on Google Earth. You can browse through and click on a list of important places in both polar regions. For further investigation and analysis of the polar regions you can activate a number of Google Earth layers within the Frozen Planet display. The display also includes videos about each region although the playlist for the Antarctic region is much longer than the playlist for the Arctic region.

Applications for Education Frozen Planet: 
Explore the Polar Regions could be a good resource for both science and history teachers. In fact, Frozen Planet could be the basis for an interdisciplinary unit at the middle school or high school level.

Here's a fun fact that I learned through Frozen Planet: Explore the Polar Regions, five years after being the first person to stand on top of Mount Everest Sir Edmund Hillary was part of the team that completed the first complete crossing of Antarctica .

Geospatial Hydrologic Modeling Extension (HEC-GeoHMS)

The Geospatial Hydrologic Modeling Extension (HEC-GeoHMS) has been developed as a geospatial hydrology toolkit for engineers and hydrologists with limited GIS experience. HEC-GeoHMS uses ArcView and the Spatial Analyst extension to develop a number of hydrologic modeling inputs for the Hydrologic Engineering Center‘s Hydrologic Modeling System, HEC-HMS. ArcView GIS and its Spatial Analyst extension are available from the Environmental Systems Research Institute, Inc. (ESRI). Analyzing digital terrain data, HEC-GeoHMS transforms the drainage paths and watershed boundaries into a hydrologic data structure that represents the drainage network. The program allows users to visualize spatial information, document watershed characteristics, perform spatial analysis, and delineate subbasins and streams. Working with HEC-GeoHMS through its interfaces, menus, tools, buttons, and context-sensitive online help allows the user to expediently create hydrologic inputs for HEC-HMS.

HEC-GeoHMS can also generate tables with information on the physical characteristics of water bodies and watersheds. This information is useful when estimating hydrologic parameters.

Additional features include:

• Data Management: This feature aids in managing the locations of different projects and can also be used for error checking and detection
• Terrain Preprocessing: This can be done in two modes: step-by-step or batch. In step-by-step mode, the user can examine the model outputs and modify the data set as needed. If the user is confident in their data set, they can opt to run this feature in batch mode which eliminates additional steps and runs unattended.
• Basin Processing: The user can divide the basin into subbasins (or merge subbasins together) with the results displayed instantaneously. This allows the user to make modeling decisions on the fly, rather than waiting until the end to run the model and then make modifications.

Basic Inputs:

• Watershed and subbasin information (boundaries, sizes, stream locations, etc)
• Pre-preared data to apply over the watershed grid
• Topographical features and drainage information

Basic Output:

• Spreadsheets and datasets describing watershed and subbasin characteristics
• Spatial analysis result datasets
• 2-D and 3-D images including topography, and stream and water body locations
• Data that can be imported for simulations run in HEC-HMS

How to Run the Model:

• Import or construct a watershed with subbasins. You can import a file made with HEC-HMS, or use HEC-GeoHMS to build a new one.
• Modify the watershed, subbasins, and their characteristics as needed
• Import pre-assembled data to associate with the site. Be sure that the data is compatible with GIS data structures. If you are unfamiliar with GIS data analysis methods and techniques, you may wish to read over some examples in the HEC-GeoHMS users manual.
• Run a simulation/ perform you analysis and view the results. You may also export the data to HEC-HMS to perform additional hydrologic modeling
