Review of Building Web and Mobile ArcGIS Server Applications with JavaScript by Susan Nash

It is not easy to find a GIS web app builder that takes you all the way from the basic initial steps of familiarizing yourself with HMTL, CSS, and JavaScript to fairly complicated web applications. Building Web and Mobile ArcGIS Server Applications with JavaScript, by Eric Pimpler has two main advantages: first, you can use high-quality GIS data (or at least data that is specific to your needs), and second, you can create light apps that work quickly over a number of different devices. You’re not likely to have obsolete apps using HTML 5 and JavaScript, so it is good that the text guides you and helps you use HTML 5 and JavaScript.

The book is very logically organized, and it takes you step by step through the entire process. You start by creating a base map, and then add layers of data to the map, and then have it all display as a web page. You’re able to add different types of data layers, which include tiled, dynamic, and feature. The section on adding data layers is very robust (as it should be), and it’s followed by adding Graphics to the Map. It’s important to keep in mind that the graphics layer sits on top of the other layers – so, some data management / housekeeping / filing protocols and customs are very helpful here. In this book, the basemaps are provided by ArcGIS Online.

For a person who does not work with GIS data or ArcGIS every day, it’s probably best to work through the examples and see how they’re being developed. In that case, I’d look at chapter 8, “Turning Addresses into Points and Points into Addresses,” and then work through the example a couple of times. The chapter covers geocoding, which is at the heart of web mapping applications. It’s the way you turn physical addresses into latitude and longitude coordinates.

The book clearly demonstrates how to write and test the JavaScript code in the JavaScript Sandbox, and then it gives you a chance to practice. I also like the little tips and tricks – example, use Notepad++ instead of Notepad for coding (to avoid the extraneous code problems of Word, etc.).

In addition to Geocoding, there is a very clear and easy-to-follow chapter on using Geoprocessor, which is very good for developing models.

The appendix gives an example of using ArcGIS templates and also Dojo in order to develop user interfaces. This section alone is worth the price of the book. The instructions are very clear and the screenshots appropriate and easy to follow.

Some of the chapters contain a great deal of code and not perhaps as much detailed explanation as might be useful for people who are fairly new. It would not be a bad idea to have more call-outs in the code to point to what exactly is happening.

Overall, this is a great manual – very practical and extremely timely.

Just a last thought -- when you first read the title of the book, Building Web and Mobile ArcGIS Server Applications with JavaScript, you may immediately ask yourself two questions: first, why ArcGIS and why not Google Earth or Google Maps integrated apps?; and second, why JavaScript?

First, ArcGIS Server is the most popular and widely-used platform for developing GIS applications for the web. It uses many different dynamic map sources, and is not tied to just one (such as Google Earth). So, if you use ArcGIS Server, you can incorporate the best possible map sources / GIS information.

Second, JavaScript works really well with modern web browsers (Internet Explorer, Firefox, Chrome, and Safari), and it works well with HTML 5. This allows maximum flexibility with mobile applications. Using JavaScript in web applications will optimize performance because the applications are dynamic and do not have to return to the server for data. As a result, they are very responsive and use-friendly, not to mention that they are also faster.

Geospatial Advancement Canada 2014 (1)

This Monday started the Geospatial Advancement Canada 2014 conference. The conference aims at discussing Geospatial trends around a National Geospatial Strategy for Canada.

If you would like to follow the conference discussion on Twitter, search this tag: #gcan14.

Here are some of the main speakers and key elements of presentations held on Monday:

  • Major General Christian Rousseau explain the role of its GeoSpatial Intelligence Group that needs to find ways of spending less time looking for information and more time for geospatial analysis;
  • Julie Lefevbre expose the main projects of R&D in Defense & Security such as Arctic Intelligence and situation awareness (e.g. MASAS) in Canada, but also what she sees as the future of cloud-based architecture that might be built on collaboration (e.g. Virtual USA, US GeoSpatial platform) and knowledge;
  • Steeve Guillemette present the case of health crisis management in Québec City during legionnaires disease outbreak and how geospatial analytics become the main integrator of information gathered by specialist;
  • Gido Langen explain how he sees 3rd Generation of Web Mapping: establishing a network of REST end points, as the effective way of providing resources to increase quality control and improve capacity of apps deployment;
  • Richard Akerman and Deena Yanofsky identifies current limitations of most of Open Data portal which undermines standardization (e.g. common licence such as the International Creative Common 4.0, stable & unique Digital Object Identifier, etc.) and lack of intermediate tools (less developer centric) for vizualisation and spatial analysis (that might help to decrease data illiteracy & improve data skills of the general public);
  • Trevor Taylor expose his own definition of Big Data (e.g. Volume+Velocity+Veracity+Variety) and what OGC is promoting: One Open Architecture and Open Standards (e.g. not just OGC, but OASIS, W3C, Web3D) and what are the recent emphasis of OGC: Open Mobile, Internet of Things, cloud computing and privacy.

Based on the presentations made on Monday, the concept toward "built in collaboration" and "Service Oriented Architecture" is likely to be the way of doing things in the GeoSpatial world, in which at the same time the development of open and big data seems to overwhelm GIS managers and public users, but challenges the data skills of the tech guys for the good!

Slashgeo as media partner of this event will publish other articles this week on other hot topics of the conference.

Europe dotmap - 591 milion points european population density

Dear Slashgeo editor, we have released a map entitled "Europe Dotmap" which shows 591 milion points (one per person) corresponding to the european population density.

The map is obtained by merging two database sets (NASA SEDAC-Gridded Population of the World v3 and GADM-Global Administrative Areas v2) to display a simple and modern perspective of european population at municipalities level. Combining this information, the final result is a tile web map service with 6 zoom levels .
