Let's use it ArcGIS Make a nice monthly temperature map of China https://mp.weixin.qq.com/s/OuBFjJyJs4IE3E_Lh0_42Q

As shown on the cover , Our goal is to pass ArcGIS Most basic functions , Make the map shown below

Cartographic data ：2020 In China 1-12 Monthly maximum temperature data .tif

source ：https://doi.org/10.5281/zenodo.5111989

Chinese administrative division boundary vector （ National basic geographic data information base ）

First, observe what are the main elements to make it look like the figure above

1、12 How to arrange the pictures uniformly

2、 The nine segment line in the lower right corner and the South China Sea Islands

3、 Add and set the latitude and longitude nets

4、 Scale and drawing name annotation

5、 How to do 12 Pictures with different values share a color band

Then start processing one by one , Some basic operations such as data loading are no longer shown in screenshots .

• Arrange data

After the data is loaded, go to Layout view , Right click the blank space -【 Page and print settings 】, The whole page size I set is horizontal 60*40, Adjust to your own needs .

This step ArcGIS Pass through Insert data frame To achieve , altogether 12 Amplitude map , So insert 11 Data frames , Put the data of a month in each data frame , In order on the page . Then we need to make this 12 The size and spacing of data frames are the same , Lie neatly on the page .

【 The first step is to adjust the size of the data frame 】 First, adjust them ⼀ Data frame size , Then press and hold Shift Check all data boxes , Click on ⿏ Right click ,【 Distribution 】—【 Set the same size 】,12 The size of data frames can be unified . It should be noted that , Finally, select the data frame that has been adjusted in advance , In this way, the other two data frames can be consistent with their size .【 Step 2 adjust the data frame spacing 】 After the size is consistent, you can first select all the first lines , Click on ⿏ Right click ,【 Distribution 】—【 Horizontal distribution 】, In this way, the spacing between data frames is the same , Then I marked the spacing around the frame with the help of a reference line , Align the remaining two rows of data frames according to the reference line .

【 Step 3 adjust the data range and scale 】 The frame size and spacing are arranged , But there are big and small data in it , It needs to be adjusted to the same size . Right click the data frame - attribute - Set the scales to the same size .

• Add nine segments and administrative boundaries

Load the administrative boundary and nine segment line into the data frame of each month , Then insert a new data frame , Load the administrative boundary and nine segment line separately , Zoom it to the right size .

After adjustment, select the data box of the nine segment line and administrative boundary ,Ctrl+C,Ctrl+V Copy it 11 Put them on other views , Or just press and hold Ctrl Drag with mouse .

• Add longitude and latitude nets and mark longitude and latitude

Select a data box , Right click Properties -【 grid 】-【 New grid 】, First, confirm by default , After construction, it is shown in the figure , It's ugly . Adjust the attributes one by one as needed .

chart 1, I adjusted the main scale of the long axis , I felt ugly at the back, so I removed the upper, lower, left and right scale marks ,（ Uncheck up, down, left, right ）, The bottom thickness is adjusted in the border attribute , Because my data frame is adjusted to 0.5 pounds , So here is also adjusted to 0.5. chart 2 I adjusted the font of the lower longitude and latitude annotation and the direction of the left and right annotation . chart 3 I unchecked the mark of minutes and seconds , This will only show XX°, Then the direction indicator changes to show a negative sign , North and East are no longer displayed .

【 Line 】 Here you can adjust the thickness and color of the warp and weft mesh ,【 interval 】 Here you can adjust the longitude and latitude interval .

stay 【 mark 】 in , I put 【 Dimension axis 】 If you uncheck the bottom and right of the, the number will not be displayed , Otherwise, it will coincide with the figure in the following figure , It's not very nice .

Then it is set in sequence , I don't know if there is any convenient way to set it uniformly ... It can only be changed one by one （ Careful students may find that there are too many latitude labels in the middle chart , It's because I accidentally moved the data , I'm too lazy to change ）.

summary ： The adjustment options of longitude and latitude nets are trivial , Try more

• Scale and drawing name annotation

It's easy to insert a scale bar and a title , Insert a scale bar , Hold down Ctrl, Drag the mouse to copy to another 11 In a picture frame , Right click the scale bar - attribute , Adjustable scale bar style . After inserting the title, the same Ctrl+ Move the mouse to copy .

So far, it has been basically completed , There is a legend left to make .

• Set grading to 12 The pictures share a legend

First of all 12 No range of values in a graph can cover the maximum and minimum values involved , So simple color mapping is not enough . Select a layer , Right click Properties , Stretch type selection The most value , Change the high and low values to 12 The maximum and minimum values in the graph , rest 11 All the pictures are changed in this way . Then change the ribbon color as needed .

The last step , Insert legend （ Insert toolbar ）. Insert the legend and select , Right click - attribute , Select the horizontal legend in the style .

Then right click the legend -【 Convert to graphics 】-【 Ungroup 】, In this way, you can split and combine at will

Lengthen the legend , Finally, the whole thing is like this

• Export map

Be accomplished , But why is it so mushy when it's uploaded and compressed for me ？？

in general , Is to provide a brief operating procedure , There must be simpler methods and practices in the details , If you have any questions , Welcome to contact the backstage of official account .
