Teach you how to draw a map with ArcGIS [thermal map]

Today, the senior brother of the laboratory taught us to use Arcgis drawing , After learning, write a blog to record it for fear of forgetting , In fact, I don't have a comprehensive and systematic understanding of this software now , This blog estimates that it is the first time to use help like me Arcgis Let's have a hand , As for some cool operations, they are not included , But if I get 了 , Be sure to blog again to share records ~ by the way , The version I used was Arcgis10.2

 

1. Import map data + Basic settings

file --> Add data --> Add data , Then add shp file

Then you can see the picture , I have added three shp file , Can be interpreted as ps There are three layers , These three layers are “ county ”、“ City ”、“ province ”.

Knowledge points are coming ！！ On the blackboard

• Check the box next to , You can choose this layer to display or hide .（ Too simple , No demonstration ）
• Each layer can be changed by dragging , Who is in the front , Just show who .（ But be careful , I have to point out what I marked , That is, select in “ List in drawing order ” Only in this mode can you drag , Otherwise, it cannot be dragged .)

• You can display multiple layers by setting transparency

Right click the layer you want to set , choice “ attribute ”, stay “ Show ” Set transparency inside . In this way, you can see multiple layers at the same time ！

• Set map provinces / City / County fill in the blank , Outline thickness 、 Color .

Click the color block of the corresponding layer , Enter the setting interface , Follow the prompts to set .

Then you can see the length of the figure after setting ~

2. Import numerical data + Basic settings

Next, import some numerical data , Draw a heat map , The data is different City To classify , It is divided into 11 class . Because I want to classify cities , So the fields in my data are [ City name s1-id, type ,...], The data is imported here , I hope sid This field can be associated with the city name of the map , In this way, you can automatically pair , Then make a picture ~

Because it is the classification of cities , So I chose “ City ” This layer , Right click , choice “ Connection and association ”-->“ Connect ”

1. yes shp Fields in the file , Choose the city
2. Is the data file to be connected , I'm here for a excel
3. yes excel Inside the city column and shp The matching field in the city （s1-id The value of the field is Beijing , Chongqing City ... These city names ）

After import , May exist .shp The city name in the file does not match the city name in the data table , As a result, it cannot be related , It needs to be modified at this time .shp The city name in the document , Unify the two ！

（ In fact, it is possible to change the city name in the data sheet , But elder martial brother said , If there are multiple data tables to draw, you need to change them many times , Change directly .shp Only change the file once , Be smart, hahaha ）

After the data table is opened , Ascending order , You can immediately find the city that doesn't match .

There are two possible reasons for not matching .1. shp and excel The city names are inconsistent   2.excel There is no such city

Statistics are needed for the first kind , You cannot directly modify this table now , Need to open edit mode , Then you can modify the table directly

The watch is done , Then right click the city layer , choice “ attribute ”, Enter layer properties

The value here , It is the value of each city corresponding to the data table I imported , class , Just a few different colors . Click OK to draw the picture ！

3. Derived data / picture

In this way, data is exported , You can continue editing next time

In this way, the exported image ,pdf And many other formats are available ~

 

TIPS： Just installed Arcgis The font of the toolbar is very small , I suggest you increase it . Right click first Arcgis The icon , choice “ attribute ”, Then operate as shown in the figure ：
