Hurricane Matthew leaves lots of rain
The Hurricane Matthew may be weakening, but it doesn't stop it from leaving huge amounts of rain for Central America. This rain has led to flash floods and dangerous mudslides. The wind speeds have also decreased to 35mph. No warnings have been declared for coastal regions, but Belize and Honduras have issued tropical warnings for there countries. As Matthew keeps moving it will keep moving northwest and will slow down and become stationary. Still the damage from the rain could be life threatening to Central America.

Historic trail in danger
In Nevada County, there is a dispute over a Historic Trail. This trail was a emigrant trail that help travelers in the 1800's travel to California. Some people are trying to get easements in place so that the path this trail was on does not became private property. Homeowner asked the Nevada county to pose a year long moratorium to allow the public to have use of the trail. The people are worried about losing more of there trails. They have been saying once they lost it, it was gone forever.

Candy for using a seatbelt?
Police in Fort Mill, South Carolina, are trying a new approach to crack down on people not wearing their seat belts while driving. The police have been saying that they are tired of finding people not wearing their seat belts and them having an accident which may result in death. Their new plan is to start handing out candy to drivers for wear the seat belt, what they are given is smarties. But the people who do not wear the belts still get candy too, it is dum dum suckers. This process is to help prove to people that not all interactions with the cops are bad, instead of receiving a 25 dollar ticket you get candy. The police are finding that this is having a positive affect on the people. In my opinion I think this is a cool idea, what do you think?

The Arctic ice is shrinking
Scientists have recently reported that the sea ice that makes up the arctic has reached it's third lowest level this summer. Reports say that there was less sea ice noted in the summers of 2007 and 2008. Greenhouse gas are the main problem for the shrinking ice. The greenhouse gas are make the global temperatures raise making the ice melt. With this knowledge scientists say there may be a summer where be no sea ice in the Arctic Ocean.

Technology through the ages for Cartography
For my first post I thought I would talk about how map making has changed since the first map til the maps we make today. Map making technology has had to change to meet the needs of the new cartographers of the era. First maps had to be created by using brushes and paper. This made it hard to make multiple copies, also the earlier maps were not that accurate. When the compass came around, it made future map far more accurate. The printing press was a big part in map making, it helped make mass production of maps. Land surveying was help with the the telescope and also the sextant, with these the map makers could find the latitude by measuring the angles. Also another technology that was used was photochemical technology, which helps shorten the time it takes to remake and reproduce a map.
When the 20th century rolled around, computers took over with making the maps. With the help of image processing and database management, maps have greatly improved from its earlier counterparts. New software like CAD and GIS make changing details in a map much easier. This leads to real time mapping which is used a lot now a days. So in conclusion, the technique and technology has rapidly changed from the beginning of the first map to now, and it is always changing
