At the parent meeting, the teacher did these four questions on the blackboard:
2 + 2 = 4
4 + 4 = 8
8 + 8 = 16
9 + 9 = 20
Parents said: "You miscalculated."
The teacher turned around and said slowly: "Yes, everyone sees clearly, this question is wrong. But I have counted three questions correctly, why no one praised me, but just saw me The wrong one! "
The teacher then said meaningfully: "Parents, the true meaning of education is not to discover the mistakes of children, but to appreciate what they did right."
Comprehension:
The same is true of being a human. You treat him/her nicely for a hundred times, maybe he/she has forgotten; once he/she is unsatisfactory, he/she may obliterate everything!
This is the humanity principle of 100-1 = 0.
This is true between friends, as well as between relatives and families.
This topic is mentioned today in order to make friendship last forever and affection forever.
Take a step back among friends, and make a step higher among loved ones.
Thanks to the grace of dripping water, one should return a fountain of water.
Some people might hope that, in their own lives, someone would appear like a lamp who can give one or two advises of guidance to them about life.
After experiencing the ups and downs of life, I discovered that much of the wisdom of life is actually hidden in the bits and pieces of life.
If the rooster calls the sky, it will shine. If the rooster does not call the sky, it will still shine. The key is not if the rooster has called the sky to shine, the key is that who has waken up from the call.
When one wakes up, a day is passed; when one does not wake up, a whole life is passed.
Comprehension:
Waking up every day is a new life.
Living healthy is the most important and happiest thing in the world.
Take advantage of the sunshine, go out for a walk! The grass, the trees, the flowers and the birds in this world are all beautiful. Don't let this wonderful time pass.
Overall, I am very happy that I take this Geography 7 class. With the guidance of great TA Jida and Professor Shin, my interest and sense of satisfaction in ArcGIS are further developed. Revising all the 8 labs I have done, I feel amazed about the ability I have learned for manipulating and applying GIS into mapping. In the first lab, I introduced the characteristics of the places I lived using different maps. This assignment has aroused my understanding that different maps have different purposes. For instance, I used the weather forecast map to illustrate the moving direction of storm in Hong Kong. Next, we studied about map reading and scale conversion in the second lab. We also gain knowledge of identifying quadrangles, UTM zones, magnetic declination, and geographical coordinates as well as cropping out a feature from a map. In lab 3, I can create my own map using Google map. That was my first time to generate a route with all the geographical features. Most importantly, I realized the potentials and pitfalls of neogeography. Furthermore, I practiced to utilize ArcGIS to produce different map layouts, integrate them with research, and analyze the results in the latter five labs. For instance, I engendered a proposed airport expansion map layout with titles, legends, scale bars, and north arrow in lab 4. Moreover, I am able to comprehend conformal, equidistant, and equal area map projections because of my practice in lab 5. As for lab 6, I carried out hillshade, slope, and aspect maps of DEMs using ArcMap. More interestingly, I was able to make and visualize a 3 dimensional map due to Arc Scene. In addition, lab 7 allows me to reflect and interpret the temporal pattern of station fire in California on a map. Last but not least, I understand how to show spatial distribution and population density of different races and analyze the data in the last lab. Therefore, I have absorbed so much useful knowledge and techniques in this class. I appreciate the opportunity to study Introduction to GIS so I will recommend other students to take it.
I selected the approximate area of SequoiaNational Forest. The map’s spatial reference is NAD 1983 UTM Zone 11 N and the central Meridian is -117. The forest is located in the southernSierra Nevadamountains of California. Thenational forestis named for the majesticGiant Sequoiatrees which populate 38 groves within the boundaries of the forest.It also covers 1,787.87 square miles (4,630.55 km²), and ranges in elevation from 1,000 feet (300 m) in the foothills of the Sierra Nevada to over 12,000 feet (3,700 m).The full extent of the area I posted is around -118.9014 degree for the left, -118.4361 degree for the right, 36.1952 degree for the top, 35.8693 degree for the bottom. Its columns and rows are 1463x1255. Its cell sizes X and Y are both 28.2525103 meters. There is only one band. Moreover, the area’s grid format is continuous source type. The slope map's mean is 18.96, while hillshade map’s mean is 170.208. Furthermore, the aspect map’s mean is 189.9564. Last but not least, I exaggerate the 3D map by multiplying 10 times with a base height of 10000, resulting in 100000 for Z unit conversion.

This assignment will be finding three interesting maps and writing one paragraph about each map. I also need to identify the source of the maps, describe the maps, and discuss what I find interesting about the maps. Therefore, I found 3 maps online, which are closely relating to my life.
This map is about California population. Most people live in San Francisco, Los Angeles, and San diego. This illustrates that these are major areas in CA. The map implies that CA's five largest cities are Los Angeles, San Diego, San Jose, San Francisco, and Long Beach, and its capital is Sacramento.
I found this map interesting because I am now living in LA, which is one of the largest cities in CA. I learn more about population growth in CA. California's population growth includes natural increase and international immigration. A high population density may create the problems of traffic congestion, pollution, and crimes. However, more people bring more transactions and financial activities. I enjoy living in LA now, but traffic jam here is really serious.
This map is about roads in Washington state (WA). As we can see from the map, Washington's North-South interstates include Interstate 5 and Interstate 205, while its East-West interstates are Interstate 90 and Interstate 82. Moreover, Route 2, Route 12, Route 97, Route 101, Route 195 and Route 395 are US Highways and State Routes in Washington. Cities with populations over 10,000 are Aberdeen, Anacortes, Auburn, Bellevue, Bellingham, Bremerton, Burien, Camas, Centralia, Kennewick, Des Moines, Edmonds, Ellensburg, Everett, Federal Way, Issaquah, Kelso, Kent, Lacey, Lakewood, Longview, Marysville, Moses Lake, Mount Vernon, Mountlake Terrace, Mukilteo, Oak Harbor, Pasco, Port Angeles, Pullman, Redmond, Renton, Richland, Seattle, Shoreline, Spokane, Sunnyside, Tacoma, University Place, Vancouver, Walla Walla, Wenatchee and Yakima.
I like this map because it shows all the cities' names and boundaries in WA. I lived in there for 2 years, and I stayed mainly at Bellevue and Seattle. I can calculate the land area of WA from this map, which equals to around 66,544 square miles.Many people may misunderstand that Seattle is Washington's capital, but Olympia is truly the capital of the state. Because of the rainy weather in WA which facilitates plants' growth, WA's nickname is Evergreen State.
This map is about tropical cyclones around Hong Kong. Amongst the five cyclones, Lionrock necessitated the issuance of tropical cyclone warning signals in Hong Kong. According to the map, Lionrock formed as a tropical depression over the northern part of the South China Sea about 600 km south-southeast of Hong Kong on 28 August and moved northwestwards. It intensified into a tropical storm the next day and turned to the north.
Being a Hong Kong citizen, I feel that one of HK's specialities is having typhoons.Therefore, this map is interesting to me. When I saw this map, I got more familiar with five tropical cyclones formed over the western North Pacific and South China Sea in August 2010. Furthermore, it indicates clearly about the longitude and lattitude of the cyclones. Therefore, this map is a very useful tool to show me the locations of the cyclones. I was spending my summer vacation in HK during that time. It is usually hot and humid during summer in the city. Honestly, I do not enjoy rainstorms. The issuance of tropical cyclone warning signals caused by Lionrock prohibited me from joining outdoor activities with my friends. As a result, I just stayed at home and did nothing.
