Where is the ob irtysh river located on a map

A Russian expedition visited Lake Zaysan in , and concluded that such a riverine invasion would not be likely. Nonetheless, a chain of Russian pickets was established on the Bukhtarma River, north of Lake Zaysan. Thus the border between the two empires in the Irtysh basin became roughly delineated, with a sparse chain of guard posts on both sides. The situation in the borderlands in the midth century is described in a report by A. Abramof Even though the Zaysan region was recognized by both parties as part of the Qing Empire, it had been annually used, by fishing expeditions sent by the Siberian Cossack Host.

The summer expeditions started in , and in their range was expanded through the entire Lake Zaysan and to the mouth of the Black Irtysh.

The actual border line pursuant to the convention was drawn by the Protocol of Chuguchak , leaving Lake Zaysan on the Russian side. Note : The above story is based on materials provided by Wikipedia.

Making sure I was visualizing the higher-resolution Airbus data in the Terrain layer was even easier than ever now that the required definition query is shown in the pop-up pane.

Ensure that the map scale is less than about , Click the Terrain layer in the map view. Copy the SQL query at the bottom of the pane to your computer clipboard. Right-click the Terrain layer in the Contents pane, click the Definition Query tab, and add a new definition query. Next, I started working with the symbology. In the Symbology pane, I chose the Bathymetry 4 color scheme. Since the bathymetry color schemes were created to range from dark blue for lower values that is, deeper waters to light blue for higher values or shallower waters , the first step was to invert the color scheme.

To do this, click the color scheme, choose Format color scheme, and click the Invert button. This made fewer of the pixels with the lowest elevations appear lighter, and more of the pixels with higher values appear darker. To make the river pop out and add some variation in the middle elevation areas, I modified the Bathymetry 4 color scheme. In the Symbology pane, click the color scheme, click Format color scheme, and edit the properties in the Color Scheme Editor.

Note: if you like what you end up with, you can click the option to Save to a style. I changed the end colors to white and black, deleted the dark blue color second from the right , moved the lighter blue color a little to the left, and added some cyan to the range of lighter colors. To really make the river pop out, I added a second white color near the end. The result was the map you saw earlier in this blog post. Because the color scheme is applied to the entire Terrain layer and the DRA feature ensures that the statistics of the current view are used to render the map, you can pan around to find other interesting locations the spellbinding landscape.
