Hello,

I’m new to the GIS world, and for practice, I’m creating a desktop application where I have to show a road map with multiple markings of equipment placed in that road section. No user interaction is needed, just the color of the markings should change according to the connectivity of the equipment. Below is the Sample.

 ![demo](https://global.discourse-cdn.com/free1/uploads/mapwindow1/original/1X/4be55c04d974ce3dde27b115012d080c8cf8d50a.jpeg)

I tried and was able to load shape files and even able to create the new shape file which mark all locations using UTM coordinate system by uploading a CSV file.

**Code to create shape file:**

static void Main(string args)  
{  
//Create new shapefile  
Shapefile myShapefile = new Shapefile();  
//Define the path of the new shapefile and geometry type  
myShapefile.CreateNew(@“F:\New Devlop try\Not Online\gisMap\Resourse\cctv.shp”, ShpfileType.SHP\_POINT);  
//Create new field  
MapWinGIS.Field myField = new Field();  
//Set the field properties  
myField.Name = “ID”;  
myField.Type = FieldType.INTEGER\_FIELD;  
myField.Width = 10;  
//Add the filed for the shapefile table  
int intFieldIndex = 0;  
myShapefile.EditInsertField(myField, ref intFieldIndex, null);

```
        System.IO.StreamReader myFile =

```

new System.IO.StreamReader(@“F:\New Devlop try\Not Online\gisMap\Resourse\cctv.csv”);  
// Using while loop to read csv file line by line  
while ((myLine = myFile.ReadLine()) != null)  
{  
if (myCounter \> 0)  
{  
MapWinGIS.Shape myShape = new Shape();  
myShape.Create(ShpfileType.SHP\_POINT);  
MapWinGIS.Point myPoint = new Point();  
myPoint.x = GetX(myLine);  
myPoint.y = GetY(myLine);  
int myPointIndex = 0;  
myShape.InsertPoint(myPoint, ref myPointIndex);  
myShapefile.EditInsertShape(myShape, ref myShapeIndex);  
myShapeIndex++;

```
            }

            myCounter++;
        }

    }

```

**Loading the shape file**

private void Form1\_Load(object sender, EventArgs e)  
{  
int intHandler1; //integer index to handle the layer  
//create a new instance for MapWinGIS.Shapefile  
[//MapWinGIS.Shapefile](https://MapWinGIS.Shapefile) is a data provider for ESRI Shapefile  
MapWinGIS.Shapefile shapefile1 = new MapWinGIS.Shapefile();  
//Define the data source for MapWinGIS.Shapefile instance  
shapefile1.Open(@“F:\New Devlop try\Not Online\gisMap\Resourse\cctv.shp”, null);  
//display the layer on the map  
intHandler1 = axMap1.AddLayer(shapefile1, true);

```
    }

```

This is what I’m able to do till now:

But after this, I’m clueless about what to do or how to proceed further. As it’s not near to what I’m trying to achieve. any help will be a great help.
