GIS is big and its applicable everywhere, in data, businesses, helping NGOs, even for transport companies. We here at Geospatial Trends, help you find these trends easily and see the market move to your advantage. Watch this space.

Dimensions in Geospatial Modeling

“Space” and “Time” are of great importance in today’s times more than ever before. Our cities are expanding, land is reducing, our natural and social environment is changing. Nothing seems permanent anymore.

Driving around one of India’s great cities, Mumbai gives you a great sense of this change. Where newer buildings are coming up, the great old slums of Bombay still exist.

Even a seemingly slight change in the city, causes the planners of this great city to consider so many factors, when planning any new infrastructure or maintaining the old ones. Take travel for example. Mumbai’s local train transport system has been the backbone of connectivity in this great city.

But are our trains getting less crowded by day? The city is still expanding, with increasing population and the capacity of our roads decreasing, time is never going to increase. Time has to be made out of our busy schedules, to travel the vastness of this city, eventhough there is traffic, there are crowds on our trains, buses and our roads. People still have to get to work on time, children need to get to school, supplies for this great city have to be delivered, and deadlines have to be met. It brings it down to the dimensions of space and time, and a number of factors, environmental, political and social that affect these dimensions.

Geographic information since the beginning has helped us understand space. Now with advancements in Geospatial technologies, we are able to quite accurately model and depict geographic information in the context of spatial (space) and temporal (time) dimensions. Geographic information can help visualize our space in 3d, and to add to that we have time.

Temporal aspect of geographic data, is so significant in our time. Geographic data collected over years, and decades, along with other non-spatial information, not only gives us a great understanding of land use and climatic changes but also helps us predict such changes in future. It is this depiction of our 3 dimensional space along with time, that gives rise to our 4D Geospatial information. And to add to this, is also a new dimension, which is scale.The scale factor helps us model changes better in the context of specific localities, or a specific country or  countries all over the world.

The advancements in capturing geographic information, through remote sensing and surveys, and the advancements in our ability to model these dimensions, along with so many other, helps our governments, and city planners effectively tackle changes in our space.

Online GIS- A new step forward through ArcGIS Online

GIS welcomes Cloud Sharing

Building web maps and sharing information on the cloud, has become easier through services like those offered by ESRI. ArcGIS Online is a new way forward in sharing maps, map applications and using this platform to use services from arcgis online, bing map and even ArcGIS Server.

This works through the system of credits, where credits can be purchased and used for using basemaps, data, analysing data, creating mapping and other analysis services.

Cloud GIS – Pros and Cons

Everything these days seems to be heading to the cloud. You can store your documents, images, contacts, calendars, presentations, articles, accounts, everything in the cloud. So it just seems logical that GIS is also heading that way. Most of the leading GIS vendors have developed Cloud GIS solutions or certainly thinking about it and a growing number of private companies are also dipping their toes in the market. This article has not been written to compare the various solutions on the market, although I may look at doing this in an upcoming article, but just to look at some of the broad advantages and disadvantages of cloud GIS.

Having said that, some of the big players currently include Map2NetArcGIS OnlineGIS CloudMapBoxMango MapCartoDB and MapInfo Stratus. I am sure there are many more on the market or about to hit the marketplace, so do you due diligence before jumping into this emerging way of getting your GIS out to the world.

Advantages for Cloud GIS

  • Data Access
    • Access can be via any internet connection, anytime, anywhere. I see this as both an advantage and a disadvantage, if you have a good internet connection then it is great but if you do not then it will quickly become a source of frustration for your users.
  • Distribution
    • If you have a range of remote users then cloud GIS makes the distribution of your data, analysis and systems very simple. No need to send data using DVD or downloading large datasets to update a local server.
  • Data Capture
    • Having a cloud GIS allows data capture in real or near real time to be displayed directly onto your system. There are also many successful applications of where data has been captured by the general public and verified by users. One such success story is open street maps.
  • E-commerce
    • The ability to sell your data or online services to a wider audience can open up the income streams for your organisation through cloud GIS.
  • IT Management
    • The need to have dedicated GIS Administrators will be reduced as you can outsource that to the cloud GIS hosting organisation

      Disadvantages for Cloud GIS

      • Data Access
        • Access can be via any internet connection, anytime, anywhere. I see this as both an advantage and a disadvantage, if you have a good internet connection then it is great but if you do not then it will quickly become a source of frustration for your users.
      • Security
        • Security is an important aspect of any system and you will need to make yourself sure that the cloud GIS hosts have good security in place so your data is not accessed by users who should not be accessing it.
      • Data Volume
        • GIS data has always been big, taking up gigabytes on your own server. If you move to a cloud GIS solution then there is both the time to migrate the data to the host server and also for end users to access and download. There is a lot of clever sampling software out there for web-based GIS so the end user may not notice and issues if just viewing but downloads maybe a different issue.
      • External Hosting
        • This can be a major concern as the cloud GIS hosting organisation may not have your best interests at heart. They are a business after all and in it to make a profit but they will also be striving to provide you with a valuable service so they do not want things to go wrong.
        • What sort of back-up and redundancy systems are in place with your cloud GIS host. Make sure that they are not backing up your data during your business hours or if they are that it does not impact on the delivery of your service. Remember that cloud GIS servers can be based anywhere around the globe and what is midnight for them might me 10am for you.
        • Is the cloud GIS host offering you a dedicated server, if not who else is sharing it. What sort of load is there system but for.
      • Lack of Control
        • Another downside of cloud GIS, is the lack of control you may have over the way your data is used, displayed, manipulated and analysed. To add a new function or layer may not be as simple as just loading a new dataset onto the server.
      • Data Format
        • What formats is the cloud GIS application serving the data out in. Do you need to reformat your data?

      There are a lot of advantages and disadvantages to cloud GIS but it looks like it is something that is here to stay and maybe worth looking at as a way to simplifying the needs of your organisation and the needs of your users. Look for a service that meets your needs, your data formats, your end users and the level of control you want.

Disaster management through GIS

GIS has been very instrumental in the fields of disaster management, be it cyclones, the Haiti quake and the more recent earthquake of 7.8 magnitude that rocked Nepal, claiming thousands of lives and damages to property, and national heritages as well.

Many mapping agencies like ESRI, Open Street Maps have helped in identifying regions that have been hit and planning out rescue operations. The International Centre for Integrated Mountain Development (ICIMOD),based in Nepal, has set up a dedicated webpage to provide the latest maps, data and information regarding the earthquake to assist in the relief operations
