Remote Sensing and Land Cover Change

Remote Sensing and Land Cover Change | Porter Geography | Scoop.it

By moving the slider, the user can compare 1990 false-color Landsat views (left) with recent true-color imagery (right). Humans are increasingly transforming Earth’s surface—through direct activities such as farming, mining, and building, and indirectly by altering its climate.


This interactive feature includes 12 places that have experienced significant change since 1990.  This is an user-friendly way to compare remote sensing images over time.  Pictured above is the Aral Sea, which is and under-the-radar environmental catastrophe in Central Asia that has its roots in the Soviet era's (mis)management policies.

Shanelle Zaino's curator insight, October 22, 2014 2:24 PM

Looking at the images above it is understandable that the disappearance of the Aral Sea is known as the greatest environmental disaster (that we are not talking about). The amount of change that has taken place in this area is incomprehensible for the amount of time it has taken. Humans so often do not consider their actions on this planet , I believe what has taken place here is an utter shame.

Clearly the water level has decreased in Kazakhstan from 1990 until now. Farming, mining, and building are all indirectly changing the geography of some places. The use of rivers for cotton irrigation has shrunk by 3 quarters in the last 50 years and it is extremely affecting the Aral Sea.

Is sad to see how humans are changing the environment forcing the wild creatures to abandon the places they've been living for hundred or years or die of starvation. I wonder what will happen in 300 years when there is no more big lakes and the oceans will be completed polluted .

Making Sense of Maps

TED Talks Map designer Aris Venetikidis is fascinated by the maps we draw in our minds as we move around a city -- less like street maps, more like schematics or wiring diagrams, abstract images of relationships between places.

 

This video touches on numerous themes that are crucial to geographers including: 1) how our minds arrange spatial information, 2) how to best graphically represent spatial information in a useful manner for your audience and 3) how mapping a place can be the impetus for changing outdated systems. This is the story of how a cartographer working to improve a local transportation system map, which in turn, started city projects to improve the infrastructure and public utilities in Dublin, Ireland. This cartographer argues that the best map design for a transport system needs to conform to how on cognitive mental mapping works more so than geographic accuracy (like so many subway maps do).

When trying to graphically represent spatial information in a useful manner for your particular audience, you will have a lot to take into consideration. How familiar are the travelers with the area you map out? Are there visuals to precisely mark on the map so that will they accurately correspond to the area?

The Archipelago of Eastern Palestine

The Archipelago of Eastern Palestine | Porter Geography | Scoop.it

The shape of a state can greatly impact the political cohesion of a country as well as it's economic viability.  While this is obviously a fictitious map, it draws our attention to the logistic difficulties that confront Palestine with the Israelis controlling crucial transportation access points and corridors.   

 

Questions to Ponder:  How is the a 'persuasive map?' What are some of the geographic impacts of this fragmentation on Palestine? For Israel?

This map is persuasive because it does not show the usual Palestine. This map is fragmented and the geographic impacts it shows are the routes taken in at leisure for maritime activity and also shows the urban and popluated areas in the past and how how the sraelites impact those areas.
Matthew Jones's comment, October 10, 2012 10:16 AM
The reason this is a persuasive map in my opinion is that this map does a very good job of allowing the reader to understand the focus in which it intends to present. information key which it offers is crucial to the map b/ it help the reader better understand and analyze this map in its entirety. as far As the second question unfortunately I am not very knowledgeable as far as the impact his map as on palestiine or isreal.
Jesse Gauthier's comment, October 10, 2012 11:24 AM
This map is unique and not typical. The way that Palestine's land is severed and each transportation access point is clearly shown and highlighted, makes this map's data very persuasive and impactful. This map examines the Israelis' control of the land.
