Interactive KML Placemarks using HTML/JavaScript

Be The First To Comment
My colleague stopped by this morning and asked me to see if there is any way to  implement combo box / drop-down list in KML file for dynamically selecting the Placemarks' information. Few hour of googling come up with a quick and dirty KML (adding custom data) using HTML/JavaScript in <ExtendedData> tag with combo box selection and pasted it here for our future reference. It may helps others as well. If there are any alternatives feel free to chime in.

SOLUTION

1. Press CTRL + Z to break the 'default: Warning: Authentication failure. Retrying... or wait for few more minutes

2. Login into your guest machine - vagrant ssh , which should prompt you for password, vagrant , the default password for vagrant

3. Then go to - /home/vagrant/.ssh  and remote all the contents inside it, if the path not existed create the directory - mkdir -p /home/vagrant/.ssh

Open Source Cloud GIS System Setup with Amazon EC2 and Geoserver

Be The First To Comment
Follow these steps to set up the open source cloud based GIS mapping system.

1. Create an Amazon Web Services (AWS) account. You can find instructions for this step in the EC2 Getting Started Guide.

3. Create an Amazon EC2 instance. Instructions are also in the EC2 Getting Started Guide. When choosing an AMI make sure you choose a Windows server with IIS (and ASP.NET) already installed.

4. Connect to your Windows EC2 instance and install GeoServer. You can download GeoServer here. There are multiple setups available. Use the Windows installer. The instructions for the install are here.

5. Copy GIS data and configure map layers. The GeoServer user's manual will guide you through the steps of configuring GeoServer.

6. Start GeoServer on the EC2 instance server.

7. Seed the layers in GeoWebCache on the server. Instructions for this are here. Note that jpeg tiles are smaller than png and the default for base layers. Also png are better quality and will always be used for overlays because they can be transparent and overlays need to support transparency. Seed all layers for zoom levels 0 to 10 for EPSG:4326. If it is a base layer, seed it with jpeg files. If it is an overlay layer, seed it with png files.

Steps for setting up automatic product or build version increment using JENKINS Continious Integration server and Visual Studio for .NET projects

Part A - Configure Visual Studio Solution

1. Copy the "AssemblyInfo.cs" from your project solutions and rename into "AssemblyInfo.cs.template"



2. Add a file called "AssemblyInfo.cs.template" and replace with these two lines:
             [assembly: AssemblyVersion("#VERSION_NUMBER#")]
             [assembly: AssemblyFileVersion("#VERSION_NUMBER#")]

3. In project properties, insert this pre-build command:
     "$(SolutionDir)builder-scripts\templates\pre-build\Stamper.exe" "$(ProjectDir)\"



4. Put the "builder-scripts" folder into your solution folder. Builder scripts source
