In AutoCAD cartography sometimes we need to do some text annotation, in the industrial drawings often encounter some cubic meters, square meters, etc. with superscript unit symbol, then how to enter in AutoCAD with superscript symbol? Using multiline Text command Mtext, enter "m3^" in the text box: Using the mouse to select the 3 and "^" symbol that we need to make superscript, click the Stack button on the Text Format dialog box: Confirm the i

shirts in the reference picture, so they reduce the color concentration. I chose 3 layers of color or 3 shades of color on the palette, as I have repeatedly mentioned in my previous tutorial. When you first start at 3-4 levels, don't be a lot more. 2 levels of too much adornment, 5 levels too easy to confuse. 3 or 4 level levels are the most comfortable. You can go back to the works of any Baroque masters and experience this theory in their paintings. Figure 4: The image below will be used as a

Transformations in OpenGL include the following:The ① View (modeling)---Specify the Observer or camera position Glu.gllookat () by default, the Observer in perspective projection is viewed from the origin to the z-axis, or it can be set itself.② model (Viewing)---Move objects in a scene including moving, rotating, scaling③ Model View (Modelview)---Describe the duality of cartography and model transformations for example: The Observer is close to the o

The first chapter NURBS concept NURBs is a very good modeling method, which is supported in advanced three-dimensional software. NURBS can control the surface curve of the object better than the traditional grid modeling method, so it can create a more realistic and vivid shape. NURBs curves and nurbs surfaces do not exist in the traditional cartography field, and are specially built for 3D modeling with computer. The interior space of the 3D modelin

After the CAD model completes, in the later cartography work, in the New File dialog box enters the file name directly to open oneself establishes the model, may eliminate repeats does the layer the setup work. This article just gives you a simple example, in fact, in the CAD model Setup can also add many common settings, such as in the drawings can also be commonly

According to the complexity of the test area, from a few minutes, hours, to 1-2 days, the general survey area will not exceed half a day. The manual drawdown Assist program integrates specific tools (polygon segmentation, Attribute point selection Modification). 2: Manual Operation II: By-election of line-like figures

designThe Windows team was inspired by the design of the road signs. In these signpost designs, it is important that they remove all unnecessary elements and use the content as the core of the design, which they introduce into the WP7 design to allow the content to speak. The interface disappears and the content is the new interface. Now the interface is not a way to get content, but the content itself. Reduced visual design emphasizes the direct interaction between the user and the content (di

Fortunately, there is a Datetools MIT protocol, and after thorough testing, you can rest assured of using it when you need to use the date.Auto Layout LibraryIf you prefer to write the interface in your code, you'll use Apple's hard-to-use ' nslayoutconstraint ' factory or Visual Format Language.

Many people may need to convert the longitude and latitude and plane coordinates when using arcobject. Since latitude and longitude are spherical coordinates and plane coordinates are Cartesian coordinate systems of the X-Y, This is a seemingly difficult problem. A lot of people have moved out of the projection formulas (such as Gaussian projection or mokto projection) in cartography, map projection, or surveying and plotting. They are also the refe

obtained. The command is as follows: NMAP-SV-P 80-v-script default, HTTP * 192.168.1.1 From this, we can see that NMAP scans the port 80 of the other party and then uses a large number of scripts starting with HTTP to scan it. The scanning process found that in the HTTP-auth script execution, the words "Basic relm = TP-LINK wireless n router wr740" appeared (red line part ), the type and version of the target device have been mined. If we know more about the vulnerability wr740, we can perform

about my hard work after graduation, the university must learn the true skills. Okay, that's the end. The definition of GIS has been very vague. Some people suspect that it is pseudo-scientific in the Post. Most beginners feel very abstract and do not know what GIS can do or what it can be used. First, let's take a look at the real existence and function of GIS and try to make it less abstract. I don't know if the kindergarten children have been in touch with the map. It took too long to rememb

in your model is that you can associate an icon with a class, which is more intuitive, easy to understand, and easy to read, and even for people who are not familiar with UML. In IBM Rational Rose, you can expand the graph toolbar in a user-friendly way so that you can create a model class by clicking the mouse and the expected prototype name has been defined.I recommend that you start with your expected prototype name by using the abbreviations in the plotting method. That is to say, the names

After two years of college time, I constantly learn the knowledge of surveying and mapping and master a lot of professional skills, first through this professional name, everyone should be able to think, surveying is generally measured and then cartography, then in fact, it is true. Early, the mapping is what hard, of course, now may not be easy, haha, but, after continuous development, mapping also into a lot of new technology, at that time is a pers

1 Emphasis on map projection knowledge Concept of projection In mathematics, projection refers to establishing the correspondence between two surface point sets. In cartography, map projection is to establish a one-to-one correspondence between the surface and the projection plane, that is, to study how to express the earth surface to the map plane.Importance-correct map

Grid-the grid structure is the simplest and most direct spatial data structure. It refers to dividing the earth's surface into a grid array of uniform and closely adjacent sizes, each grid is defined by rows and columns as a pixel or pixel and contains Code Indicates the attribute type or value of a pixel
