Simple Directions

    After taking an unintended long break after the 100th post, I am back with more examples and several more GIS news. Today, we will take a look at a simple example showcasing the use of the Google’s Directions Services. Using the Google’s Direction service, we can calculate the distance between two points, show the path between these two points, calculate the average time taken to traverse this distance and we can also enforce several constraints on this path.

    The Google Directions API is a service that calculates the directions between locations using an HTTP request. You may pass either an address (string) or a latitude/longitude coordinate as the origin and destination. If you pass an address as a string, the Directions service geocodes the string and converts it to a latitude-longitude coordinate to calculate directions. The origin and destination are two mandatory parameters for a directions request, whereas several other optional parameters like mode of travel, waypoints, avoid tolls, avoid highways, etc. are also used. We will be having a look at each of these parameters in subsequent examples.

    Today, we will have a look at a simple piece of code which will show a path between two pre-defined locations Pune and Mumbai in India (hard-coded example) using the directions services. Let us have a look at the code directly. I have commented the code where ever necessary.



    The output of the above code will appear as seen in the result section above. Two labeled markers will appear at the origin and destination address with a purple polyline depicting the route between the two locations. In later examples, we will see several more complex examples using the Directions Service.

    If you have any queries/ doubts regarding today’s code, please leave a comment! Hope you find this example helpful!

Difference between word-break: break-all versus word-wrap: break-word

The 2 CSS properties word-break: break-all and word-wrap: break-word appear to work in the same way or generate the same output, but there is a slight difference between the 2 and we will be discussing these differences today.



    Take a look at the example above. The difference is quite evident, however I will try to explain it further.

word-break: break-all Irrespective of whether it’s a continuous word or many words, break-all breaks them up at the edge of the width limit even within the characters of the same word
word-wrap: break-word This will wrap long words onto the next line.break-word adjusts different words so that they do not break in the middle.
    So if you have many fixed-size spans which get content dynamically, you might just prefer using word-wrap: break-word, as that way only the continuous words are broken in between, and in case it’s a sentence comprising many words, the spaces are adjusted to get intact words (no break within a word).     In case you want to exp…

Geodesic, Draggable Onclick Polygon

After creating a simple polygon and then creating an on-click polygon, we will today see how to create a polygon which can be changed, altered, dragged; basically edited on the fly. We will also cover the geodesic polygon in this example itself. If you want to read and understand more about what "geodesic" is, read this post.

    Nothing exceptional about the code that I think needs explanation! You can create a geodesic polygon which can be edited on the fly. Click, hold and drag any marker, and the two polylines connected by this marker will change accordingly. By clicking on the marker, that marker would disappear, and the polygon will reform itself! Here is today's code.


    You can copy the above code in a text file and save it with .html extension. Click on this file; it will open in your default browser and you will see an exciting map in action! The output of the above code appears as seen in the result section above! If you have any doubts or queries regard…

Onclick polygon

Yesterday we had a look at a simple polygon example. But that example was not exciting as it was all hard-coded with no user interaction and which means no fun! Today's example will deal with creating a polygon on the fly, i.e. an on-click polygon in action!

    The code for creating a polygon is very much similar to creating a polyline! The only difference is that you need to replace "Polyline" by "Polygon" in such examples. Let's head on to our code.


    The output of the above code can be viewed in the result section above. If you have any doubts or queries regarding the above code then please comment here or feel free to drop me a mail! Till then, happy mapping!

Jquery Mobile - Readonly listview

The Jquery Mobile Listview that is used generally used to link each list item to a new page in the application or to link that list item to another list. However, it is not always necessary to have a linked list. Sometime we need to display a list that does not have to be linked to anything else.

    Using Jquery Mobile, we can have non-interactive, read-only listviews in our web pages. This list can be generated using the ordered or un-ordered lists that don't have any linked items, i.e. we basically do not include any anchor tags within our list item tags. This will render the listview as a non-interactive, read-only listview.

    Take a look at the JsFiddle below. The code and the actual result will give you a better picture of how you can implement the non-interactive, read-only listviews.



    Hope you find this example useful. Please drop a comment if you face any problems or have any queries. I would be happy to help and learn more. You can take a look at more examples …
