If you remember my last blog that I present an interactive map host via ESRI ArcGIS Online. After my data was successfully uploaded, I found several issues that I don’t like about it:
- Even though ESRI ArcGIS Online have a super nice format that you could visualize the spatial data in a pretty way, but the data loading from the site is very slow, AND IT’S COULD BE VERY EXPENSIVE. I am at my 60 days free trial at this point and I believe if I wanna use the server and do some data analysis on ArcGIS Online I have to buy their credits;
- The way of data presenting is restricted to the certain format depends on how you select the web map format from ESRI.
I use quite a bit of R, and I know that there are two packages in R called Shiny and Leaflet For R might help me develop the idea. I was so thrilled to find these packages, I feel a bright light shine on my road and point to the destination I wanna head to, and I found a perfect example that my web map application will look like especially the case of American Super Zipcode. There are not only an interactive map but also while you zoom in and out you could also show some statistic results on the right side of the map. It’s too cool.
But I was so disappointed too while I found out developing a web application through Shiny and Leaflet for R would not be free, because I still need a server to host my data and APP once they could be share. However, at the point that I only need to test my ideas.
