Dr. Snow's Map

Dr. Snow's contribution to epidemiology and cartography is very significant. His map of Cholera deaths and water pumps became a foregoer of spatial analysis. This map represents Cholera deaths occurence of Dr. Snow 's analysis, which was created in the early nineteenth century. 
 

Kindergarden Distance Analysis

ArcGIS Online allows to solve spatial tasks in various ways, specifically - plan routes, find nearest paths, chose appropriate place to go, analyze hot spots and other patterns. Following map represents kindergartens with a minimum 25 places, which are not far than 500 meters from Salzach river, glass waste containers and a motorway.

Store's visual impact

Number of residents and tourists in Salzburg grows. Therefore investors decided to built a big store in Salzburg, since there are few of them. There are some main requirements for a new store: the area have to be 10000 square meters, a new building have to be near Salzach river as a main attraction of the city, store have to be visible as possible in many areas. For this task I did comparison of a store with 10 meters and 20 meters height with 5 and 10 km visibility area. The main task is to analyze patterns with different heights of a new building in various viewing distances. Below the analysis that I did:

Store 10 m height with viewing distance 5 km area - 13,71 km2

Store 20 m height with viewing distance 5 km area - 23,74 km2

Store 10 m heigh with viewing distance 10 km area - 37,41 km2

Store 20 m heigh with viewing distance 10 km area - 55,09 km2

From this analysis it is obvious that a store with 20 m height will more visually affect than with 10 m height.

 

The overall process was done through 'Perform Analysis > Find Locations > Create Viewshed'. In ArcGIS Desktop in Viewshed analysis the point has to be assigned Offseta parameter. In ArcGIS Online this parameter is done in Visibility settings - the height of the building. Here is a link to a web application.

What is an average daily temperature in Spain?
 

The overall process of creating this map is next:

1. Open in ArcGIS Online new map, saving it.

2. Downloading daily weather data set, world countries (generalized) layer.

3. Creating a new layer for the study area (Spain) from the latter layer ( Perform Analysis > Find Locations > Find Existing Locations).

4. Interpolate Points of daily weather data set in the extent of Spain layer (Perform Analysis > Analyze Patterns > Interpolate points). There is a link to online map "Daily Average Temperature Map for Spain in 1st of May 2006".
